Apache - what is this symbol and why is it needed?
Apache has been the most popular web server on the Internet since April 1996. The Apache HTTP Server is an effort to develop and maintain an open-source. Server for modern operating systems including UNIX and Windows NT. The November 2005 Netcraft Web Server Survey found that more than 70% of the web sites on the Internet are using Apache, making it more widely used than all other web servers combined. The Apache HTTP Server has announce the release of version 2. This version of Apache is a major release and the start of a new stable branch and represents the best available version of Apache HTTP Server. This version of Apache is principally a security release. The Apache Software Foundation uses various licenses to distribute software and documentation for contributions from individuals and corporations, and to get larger grants of existing software products. All of the release distribution packages have been digitally signed (using PGP or GPG) by the Apache Group members that constructed them. More developer documentation on how to apply the Apache License to your work can be found in Applying the Apache License, Version 2.
To send a TrackBack, the client makes a standard HTTP request to the server, and receives a response in a simple XML format . If a client neglects to send a url, the server MUST respond with an error message. There are no length restrictions on the fields inherent in the TrackBack protocol, but server implementations are free to crop or ignore any of the request.
The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards. Online browsable documentation is also available in Version 2.
