:blackhole: - Emails addressed to non-existing accounts will automatically be deleted.
:fail: - Emails addressed to non-existing accounts will automatically bounced back as undeliverable.
400 Bad Request - The Apache Web server allows site managers to override the standard error page that is served for specific errors by number. This error, 400 bad request, means that a request for a URL has been made but the server is not configured or capable of responding to it. This might be the case for URLs that are handed-off to a servlet engine where no default document or servlet is configured, or the HTTP request method is not implemented.
401 Unauthorized -Your IP address or the username/password you entered were not correct. Your request was denied as you have no permission to access the data.
402 PaymentRequired - The data is not accessible at the time. The owner of the space has not yet payed their service provider.
405 Method Not Allowed - Your IP address or the username/password you entered were not correct. Your request was denied as you have no permission to access the data.
406 Not Acceptable - The document that has been requested either no longer exists, or has never existed on the server.
407 Proxy Authentication Required - The browser has not been authenticated on the required proxy server to access the data. This error is probably most commonly returned by content filters/parental controls.
408 Request Timeout - The browser has not been authenticated on the required proxy server to access the data. This error is probably most commonly returned by content filters/parental controls.
409 Conflict - Too many requests for the same file at one time.
410 Gone - This is like a 404 error in that the document requested is not on the server, however this differs in that the server 'knows' that the file used to be there and 'believes' that the file may be back, so it returns 410 rather 404.
411- Length Required: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) should include a 'Content-Length' specification. This is typically used only for HTTP methods that result in the placement of data on the Web server, not the retrieval of data from it.
412- Precondition Failed: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) included a 'Precondition' specification which the server detected was not met.
413- Request Entity Too Large: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) was simply too large i.e. too many bytes. What constitutes 'too many bytes' depends partly upon the operation being attempted. For example a request to upload a very large file (via the HTTP PUT method) may encounter a ceiling on upload file size set by the Web server.
414- Request- URI Too Long: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) contains a URL that is simply too large i.e. too many bytes.
Typically Web servers set fairly generous limits on length for genuine URLs e.g. up to 2048 or 4096 characters. If your URL is particularly long, you can usually try shorter variations to see roughly where the limit is. If your long URL is indeed valid, then the Web server may need to be reconfigured to allow your URLs through. Understand that Web servers have to set some reasonable limit here, because they have to deal with badly programmed clients trying to give them huge garbage URLs.
415- Unsupported Media Type: Your Web server thinks that the HTTP data stream sent by the client (e.g. your Web browser or our CheckUpDown robot) identifies a URL resource whose actual media type 1) does not
agree with the media type specified on the request or 2) is incompatible with the current data for the resource or 3) is incompatible with the HTTP method specified on the request.Detecting exactly what is causing this problem can be difficult, because there a number of possible reasons. Often the request involves transfer of data from the client to the Web server (e.g. a file upload via the PUT method), in which case you need to confirm with your ISP which media types are acceptable for upload.
501- Not implemented: Your Web server does not understand or does not support the HTTP method it finds in the HTTP data stream sent to it by the client (e.g. a Web browser or our CheckUpDown robot).
502- Bad Gateway: A server (not necessarily a Web server) is acting as a gateway or proxy to fulfill the request by the client (e.g. your Web browser or our CheckUpDown robot) to access the requested URL. This server received an invalid response from an upstream server it accessed to fulfill the request.This usually does not mean that the upstream server is down (no response to the gateway/proxy), but rather that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data. Given that Internet protocols are quite clear, it often means that one or both machines have been incorrectly or incompletely programmed.
503- Service Unavailable: Your Web server is currently unable to handle the HTTP request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. Some servers in this state may also simply refuse the socket connection, in which case a different error may be generated because the socket creation timed out.
504- Gateway Timeout: A server (not necessarily a Web server) is acting as a gateway or proxy to fulfil the request by the client (e.g. your Web browser or our CheckUpDown robot) to access the requested URL. This server did not receive a timely response from an upstream server it accessed to deal with your HTTP request.This usually means that the upstream server is down (no response to the gateway/proxy rather than that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data.
505- HTTP Version Not Supported: Your Web server does not support, or refuses to support, the HTTP protocol version specified by the client
(e.g. your Web browser or our CheckUpDown robot) in the HTTP request data stream sent to the server.The HTTP protocol has various versions identified as major.minor e.g. version 0.9, 1.0 or 1.1. Your server is indicating that it is unable or unwilling to complete the request using the major version provided by the client - other than with this error message.Assuming that your request identifies a valid major.minor version number (the request is not fundamentally corrupt), then this error should mostly only occur if you are trying to use version 1.0 or 1.1, but your
Web server only supports the older 0.9 version.

Script - A program written in a general-purpose programming language. Such languages are typically interpreted and less comprehensive than full-blown compiled languages.
Search engine - Software that searches for data based on some criteria. Although search engines have been around for decades, they were brought to the forefront after the Web exploded onto the scene. Every Web search engine site uses a search engine that it has either developed itself or has purchased from a third party. Search engines can differ dramatically in the way they find and index the material on the Web, and the way they search the indexes from the user's query.
Security - The protection of data, networks and computing power. The protection of data (information security) is the most important. The protection of networks is important to prevent loss of server resources as well as to protect the network from being used for illegal purposes. The protection of computing power is relevant only to expensive machines such as large supercomputers.
Sendmail - An SMTP-based message transfer agent ( MTA ) that runs under Unix. Developed at the University of California at Berkeley by Eric Allman in 1981, sendmail stores and forwards more mail than any other MTA on the Internet. In 1998, Allman commercialized the product by forming Sendmail, Inc. (www.sendmail.com), which offers a GUI interface for modifying the configuration file instead of dealing directly with more than a thousand lines of text. Sendmail, Inc. also offers a Windows NT/2000 version that includes the POP mail server and message store. Examples of mail clients developed for sendmail in the Unix world are elm, pine, mush and mailx.
SEO (search engine optimization) - Designing a Web site so that search engines easily find the pages and index them. The goal is to have your page be in the top 10 results of a search. Optimization includes the choice of words used in the text paragraphs and the placement of those words on the page, both visible and hidden inside meta tags. Search engines use different criteria for indexing, and those criteria may change. Thus, it becomes increasingly difficult to satisfy every one equally. Yahoo! and other directory-oriented search sites manually index a Web site, which may provide the best results for the user.
Servers - A computer system in a network that is shared by multiple users. Servers come in all sizes from x86-based PCs to IBM mainframes.

Table - A set of data elements that has a horizontal dimension (rows) and a vertical dimension (columns) in a relational database system. A table has a specified number of columns but can have any number of rows. A table is often called a relation. Rows stored in a table are structurally equivalent to records from flat files in that they must not contain repeating fields. In webpage’s it can be as simple as a spreadsheet of rows and columns, or as complex as a set of data within a database.
Tape backup - a recording system using electronic tape to store a copy of data for preservation purposes. If data should need to be restored, then the data can be found on the tape backup. Lunarpages backup data every day on every server.
tcp - (Transmission Control Protocol) one of the main protocols in TCP /IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered in the same order in which they were sent.
Telnet - A terminal emulation program for TCP /IP networks such as the Internet. The Telnet program runs on your computer and connects your PC to a server on the network. You can then enter commands through the Telnet program and they will be executed as if you were entering them directly on the server console. This enables you to control the server and communicate with other servers on the network. To start a Telnet session, you must log in to a server by entering a valid username and password. Telnet is a common way to remotely control Web servers.
Template - A set of pre-designed formats for text and graphics on which new pages and webs can be based. After a page or web is created using a template, you can customize the page or web.
Temporary URL - Lunarpages will create a temporary url for a customer if they request it while their own domain name is being registered and propagated. This is typically done when advanced web hosting functions such as php, jsp, asp, etc are needed immediately or for a testing purpose. The temp url is made into the form of subdomain.lunarpages.net where the customer can choose their subdomain name.
Thunderbird - A remote email client made by Mozilla.
Title - The title bar - the very top of the browser - displays the title of the page. The title of a web page is also displayed in search engine result pages; in minimized window titles at the bottom of the screen; and in lists of bookmarks or favorites.
tracert - a TCP /IP utility which allows the user to determine the route packets take to reach a particular host. Trace route works by increasing the "time to live" value of each successive packet sent. The first packet has a TTL value of one, the second two, and so on. When a packet passes through a host, the host decrements the TTL value by one and forwards the packet to the next host. When a packet with a TTL of one reaches a host, the host discards the packet and sends an ICMP time exceeded. Customers are sometimes asked to perform this function to determine if there is a break in communications between themselves and a remote server such as Lunarpages' servers.
Traffic - the amount of activity over a communication system during a given period of time; "heavy traffic overloaded the trunk lines"; "traffic on the internet is lightest during the night"
Trojan (Trojan horse) - An apparently useful and innocent program containing additional hidden code which allows the unauthorized collection, exploitation, falsification, or destruction of data. Most commonly associated with viruses.
Upload - Transferring a file or files from the user's computer to a remote computer.
Uptime - strangely enough, the opposite of downtime. It is defined as being the time that an item of equipment is in service and operating.
URI - Uniform Resource Identifier - URIs have been known by many names: WWW addresses, Universal Document Identifiers, Universal Resource Identifiers, and finally the combination of Uniform Resource Locators (URL) and Names (URN). As far as HTTP is concerned, Uniform Resource Identifiers are simply formatted strings that identify - via name, location, or any other characteristic - a resource.
URL - Uniform Resource Locator; an address that specifies the location of a file on the Internet (eg, http://www.fsu.edu/library).
validation/validator - An automated tool to check that coding used to create web pages is valid. It is important that coding is valid as this can impact on the accessibility of pages. Assistive technology used by disabled users such as screen readers may have problems if coding is invalid. Search engines may also have difficulty indexing pages. Most web editing packages include HTML validators or checkers, alongside spell checkers. Online validators are also available, eg W3C HTML validator and Style Sheet Validator.
Virtual host - A computer which can be forced to respond to multiple IP addresses and provide various services (typically different Web services) on each. Each of these IP addresess (which usually each have their own hostname) operate as if they were separate hosts on separate machines, although they are really all the same host. Therefore, they are called "virtual" hosts. An example of virtual hosting is when an Internet Service Provider "hosts" World-Wide Web and other services for several customers on the same computer but gives the appearence that each of these services use separate servers.
Virus - A virus is a type of program that can replicate itself by making (possibly modified) copies of itself. The main criterion for classifying a piece of executable code as a virus is that it spreads itself by means of 'hosts'. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or carrying it on a removable disk. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with worms. A worm, however, can spread itself to other computers without needing to be transferred as part of a host. Many personal computers are now connected to the Internet and to local-area networks, facilitating their spread. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms.
Viruses can infect different types of hosts. The most common targets are executable files that contain application software or parts of the operating system. Viruses have also infected the executable boot sectors of floppy disks, script files of application programs, and documents that can contain macro scripts. Additionally, viruses can infect files in other ways than simply inserting a copy of their code into the code of the host program. For example, a virus can overwrite its host with the virus code, or it can use a trick to ensure that the virus program is executed when the user wants to execute the (unmodified) host program. Viruses have existed for many different operating systems, including MS-DOS, AmigaOS, and Mac OS; today, the majority of viruses run on Microsoft Windows.A legitimate application program that can copy itself as a side-effect of its normal function (e.g. backup software) is not considered a virus. Some programs that were apparently intended as viruses cannot reliably self-replicate, because the infection routine contain bugs. For example, a buggy virus can insert copies of itself into host programs, but these copies never get executed and are thus unable to spread the virus. Self-replicating programs that have very limited spreading capabilities because of bugs should not be considered legitimate viruses.
Visits - a complete session of accesses to a certain web server conducted by one person. A visit is concluded when the customer hasn't viewed any page for a certain period of time (60 seconds in most cases).
VOIP - (Voice over Internet Protocol) The technology used to transmit voice conversations over a data network using the Internet Protocol. Such data network may be the Internet or a corporate Intranet.
VPN - (virtual private network) A private network constructed across a public network such as the Internet. A VPN can be made secure, even though it is using existing Internet connections to carry data communication. Security measures involve encrypting data before sending it across the Internet and decrypting the data at the other end.

Web services - Web services are simple, self contained applications which perform functions, from simple requests to complicated business processes. The "web services" model uses WSDL, UDDI and SOAP /XMLP. A WSDL description is retrieved from the UDDI directory. WSDL descriptions allow the software systems of one business to extend to use those of the other directly. The services are invoked over the World Wide Web using the SOAP /XMLP protocol. Each of the components are XML based. Where two agencies know about each other's web services they can link their SOAP /XMLP interfaces - provided all security concerns are managed appropriately. It is only where services are going to have unknown users that they need to be formally described by a language such as WSDL and entered into a directory such as UDDI.
web.xml - The web.xml file is used by the J2EE application server during deployment of a web module. It describes the web components used by that web module, environment variables, and security requirements. This information is stored as / WEB - INF /web.xml. For example, the default application's deployment descriptor might be stored as /usr/jrun/servers/default/delt-app/ WEB - INF /web.xml. You must add a web.xml deployment descriptor to any WAR file you want to deploy as a web application. You can then add your web module to a J2EE application, which has its own deployment descriptor (application.xml) in addition to the web module's web.xml.
