Subject Re: AJP 1.3 Connector jk/jk2
Date Thu, 13 Feb 2003 06:44:27 GMT
I actually have one site that is using the mod_jk 1.1 Apache code (that
ships with Tomcat 3.3) talking happily to Tomcat 4.1.x using the Jk2
CoyoteConnector.  (I'm doing this because I need to switch between TC 3.3 &
4.1 for testing).

If the CoyoteConnector can speak perfect v1.1 Ajp13 protocol, then it should
have no problems with v1.2 (which is what the Ajp13Connector speaks).  The
mod_jk team has put a great deal of effort into maintaining
backwards-compatibility, so that you can pretty much freely mix-and-match
Apache binaries with Tomcat Connectors.
