Uniform Resource Locator (URL, English UniformResourceLocator abbreviation) also known as web address, is standard on the Internet address of the resource. It was originally developed by Tim Berners - Li Faming used as the World Wide Web address. It is now preparing for the Internet World Wide Web Consortium standard RFC1738 a.

basic introduction to character syntax basic introduction to case-specific examples of URL in the history of the Internet, Uniform Resource Locator of the invention is a very basic steps. Uniform Resource Locator syntax is general, scalable, and it uses ASCII code to represent the Internet as part of the address. General Uniform Resource Locator marks the beginning of a computer network used by the network protocol. Uniform Resource Locator is a uniform resource identifier planting. Uniform resource identifier to identify a resource, and uniform resource locators to determine not only a resource, but also expressed where it is. For example the following uniform resource Uniform Resource Locator standard

Chi symbol to determine the Internet Engineering Task Force RFC1738, but did not say where to find one in this information: urn: ietf: rfc: 1738. The following Uniform Resource Locator is to determine each RFC1738 literature, but also determine the history of almost all of the uniform resource identifier is a Uniform Resource Locator, as described in this article so many of the elements of both for all is the same. Character syntax protocol: / / authority / path? Some of the general authorization check is the server name or IP address, and sometimes even went back a colon and a port number. It can also access the server must contain the user name and password. Path section contains the path of the hierarchical structure defined,[url=http://www.uggclearancemall.com/][b]title=UGG Boots Clearance[/b][/url], in general, between different parts of a slash (/) character. Asked to send some of the general database on the server inquiry required for dynamic parameters. Complete with part of the general mandate uniform resource identifier syntax looks as follows: protocol: / / username @ password: sub-domain. Domain. Top-level domain: port / directory / file name. File extension? Parameter = value # logo Uniform Resource Identifier Uniform Resource Identifier reference refers to a single reference (such as hypertext transfer protocol file) uniform resource identifier. Uniform Resource Identifier references an absolute reference and relative reference points. Described above are absolute uniform resource identifier reference system relative to the reference includes only special part of it located in reference to the object file that contains the reference of a relative position. Uniform Resource Identifier Reference can also be by a uniform resource identifier with a # character plus the uniform resource identifier within a marked point. This flag is not on the part of the uniform resource identifier, but let the user's browser to access the file navigation was used, so it does not actually sent to the server. Uniform Resource Locator general case is case-sensitive, but the server administrator can determine whether the case in the response to be distinguished when asked. Some servers in case of inquiries received by the different responses is the same. Address at the end of Later, Microsoft WindowsNT3.51 in its modified, you can automatically add a DNS query automatically. Number, then UNIX, NetWare also will follow up on, so the server can identify the end no domain name. However, the symbol transfer protocol server port path typical of a Uniform Resource Locator looks like this: Uniform Resource Locator URL Uniform Resource Locator URL is obtained from the Internet resource location and access method of a simple representation. URL to the location of resources to provide an abstract method of identification, and use this method to the resource location. As long as the resource position, the system can operate on a variety of resources, such as access, update,[url=http://www.uggsbootsclearance4u.com/][b]title=UGG Clearance[/b][/url], replace, and find its properties. URL contains a file name in the network-wide expansion. So the URL is on the machine connected to the Internet can access any object a pointer.

Here are some of the uniform resource locator system example: http - Hypertext Transfer Protocol resources https - secure socket layer transmission with Hypertext Transfer Protocol ftp - file transfer protocol mailto - the email address ldap - Lightweight Directory Access Protocol search file - the local computer or the Internet to share files news - Usenet newsgroup gopher - Gopher protocol telnet - Telnet Protocol I to improve the Related articles:
