ApJServMount /zone1 /tomcatZone1 problem
Using apache1.3.12, tomcat3.1
mod_jserv + Tomcat do not deal properly with rewritten URIs.
With this mount point:
ApJServMount /wdlcontext ajpv12://localhost:8008/wdlcontext1.4.0
this request:
/wdlcontext/wdlInstall?blabla
will fail because tomcat will only use the original URI passed by mod_jserv
instead of using the context set by mod_jserv.
This is very problematic when using mod_rewrite.
A patch-candidate for Ajp12ConnectionHandler.java is at the end.
Could somebody please review it?
thanks.
