Subject Re: Tomcat 6.0 with Apache 2.2 front-end
Date Fri, 30 Nov 2007 09:25:11 GMT
Tony,

mod_jk - which uses the ajp13 protocol is not the same as
the http11aprprotocol which uses http/1.1 as its protocol.

Filip - is there a comparison between apache talking to http to tomcat
vs apache with ajp to tomcat ?
