Subject RE: MOD_JK Redirection issues
Date Wed, 03 Jan 2007 09:07:41 GMT
I changed the loglevel to TRACE, But I couldn't find any new log file. The
access_log now shows

61.17.42.35 - - [03/Jan/2007:03:48:05 +0000] "GET
/APIServer/authz/list/master/AB?apikey=WEB_INTERFACE_API HTTP/1.1" 200 1350
"-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.9)
Gecko/20061206 Firefox/1.5.0.9"

61.17.42.35 - - [03/Jan/2007:03:48:44 +0000] "GET
/APIServer/authz/list/master%2fAB?apikey=WEB_INTERFACE_API HTTP/1.1" 404 314
"-" "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.9)
Gecko/20061206 Firefox/1.5.0.9"

Where the first request returns HTTP/1.1 200 and the 2nd request returns
HTTP/1.1 404.

error_log doesn't have any entries.

I tried sending the same request directly to tomcat and both
/APIServer/authz/list/master/AB?apikey=WEB_INTERFACE_API and
/APIServer/authz/list/master%2fAB?apikey=WEB_INTERFACE_API gave the correct
response and the status was HTTP/1.1 200. The second request returns 404
only when it is passed through mod jk.

Thanks
Jagadeesh

Set JkLogLevel to trace and have a look at the JkLogFile.
