I've got an odd problem. Apache is replying with a 400 error code instead of 404 when ever a client requests a non existing jsp page (html request are answered correctly with a 404). The only time Apache serves correctly with a 404 is when the request to the non existent page is to a file in the root directory. I'm aware that the root directory matches a rewrite rule but still it doesn't seem relevant.

For example:

www.xxx.com/jjj.jsp - 404
www.xxx.com/bla/jjj.jsp - 400

I've got Apache 2.2 and Tomcat 6 install with mod_jk. I forward all jsp requests to mod_jk. Here's my relevant httpd.conf input:

ServerAdmin [email protected]
DocumentRoot /opt/tomcat/webapps/sb
ServerName xxx
ErrorLog /var/log/httpd/xxx/error_log
CustomLog /var/log/httpd/xxx/custom_logs common

JkMount /*.jsp ajp13

RewriteEngine On
RewriteLogLevel 9
RewriteLog /var/log/httpd/xxx/rewrite.log
RewriteCond %{HTTP_HOST} !^www\.xxx\.com$ [NC]
RewriteRule ^(.*)$ http://www.xxx.com$1 [R=301,L]
RewriteRule ^/([\w\d]*).jsp$ /sb/jsp/$1.jsp [PT,NC,QSA,L]
RewriteRule ^/$ /sb/jsp/index.jsp [PT] [NC] [QSA] [L]

Here is an output from custom_logs

x.x.x.x - - [08/Dec/2010:09:34:40 -0500] "GET /examples/ddd.jsp HTTP/1.1" 400
x.x.x.x - - [08/Dec/2010:09:59:59 -0500] "GET /gti.jsp HTTP/1.0" 200 662

I've set up everything and mod_rewrite works properly on HTML files but not on jsp files.

I'm getting the following message in my rewrite log:

(2) init rewrite engine with requested uri /index.jsp applying pattern '^/([\w\d]*).jsp$' to uri '/index.jsp' (2) rewrite '/index.jsp' -> '/sb/jsp/index.jsp' (2) forcing '/sb/jsp/index.jsp' to get passed through to next API URI-to-filename handler

I've set up mod_jk and I can access /sb/jsp/index.jsp with no issue. I would like to have users access /index.jsp and then be rewritten to /sb/jsp/index.jsp.

My rewrite rule (notice I use the PT flag to force mod_rewrite to forward to mod_jk):

RewriteRule ^/([\w\d]*).jsp$ /sb/jsp/$1.jsp [PT] [NC] [QSA] [L]

Anyone has any idea what's going on? seems like the request is being forwarded but never gets to mod_jk.

Another thing I just noticed. If I take the PT flag out I get a different message in the log: (1) go-ahead with /sb/jsp/index.jsp [OK] And the /index.jsp instead of /sb/jsp/index.jsp So seems like apache is forwarding to tomcat but not the rewritten URL...

Thanks!
