Hi I'm using:
Solaris10, Varnish Reverse Proxy, iPlanet 7 webserver (update 8), Mod_JK 1.2.28 and JBoss 4.2.3GA My scenario: iPlanet Webserver with MODJK NSAPI plugin on Solaris10, reverse-proxied to by Varnish proxy on same server. Incoming request flow as follows: Browser (HTTP) =>Varnish => iPlanet Webserver => Mod_JK (nsapi plugin within webserver) => JBoss (via AJP protocol). Description of issue: A request comes into the webserver via the Varnish reverse proxy and is passed back to the JBoss server via the MODJK plugin, when the response comes back, the MODJK plugin inserts a Content-Length header using mixed-case ie: Content-Length: <length> (as defined in /native/common/jk_ajp_common.c), this is ignored by the webserver core as it’s expecting inserted headers to be all lower-case (mentioned here: http://www.oracle.com/technetwork/java/chunked-req-138813.html#3) and it duly inserts its own “Transfer-encoding: chunked” header, leading to Varnish being presented with a response containing both “Content-Length: <len>” and “Transfer-encoding: chunked” which breaks Varnish. Is it possible you can verify the fix and cater for this in the source so that it uses lowercase constants for iplanet/sunone/netscape builds? Currently we’re having to manually fix and compile..please let me know your thoughts.
