The Apache JServ Protocol is an efficient protocol to connect backend web servers to front end web servers.

The Apache JServ Protocol is an efficient protocol to connect backend web servers to front end web servers. It tries to be more efficient than HTTP by using header compression and preparsed data structures. AJP is mostly used to run a Tomcat backend web server behind an Apache frontend web server but there are no restrictions in the protocol to limit it to these servers.
