Something that you might not know:
- Apache is originally as a patch of the first web server developed by Rob McCool when he was working at NCSA (NCSA = National Center for Supercomputer Applications) server. It?s a short of acronym of ?A PAtCHy Web Server?
- 1999, the same folks who wrote the Apache server formed the Apache Software Foundation (ASF). The ASF is a non-profit organization created to facilitate the development of open source software projects.
- The ASF license is much more loose than GPL or LGPL, ASF is allowed to be freely redistribute the products which is under ASF license.
- If you want to integrate Apache and Tomcat there are 2 ways: AJP and WARP. AJP stands for Apache JServ Protocol, and first appeared with Tomcat 3.x to integrated with Apache server which using a mod_jserv for Apache. As Tomcat goes into version 4.x the new AJP is named as mod_jk2. WARP is another connector only for Tomcat 4.x series and provided greater flexibility and greater performance than AJP. WARP is using a connector named mod_webapp and currently is the only connector which implemented WARP protocol.
