I’ve been trying to do this for some time unsuccesfully.
I’ll say in advance that this is probably a newbie question so apologies but I do need some assistance with this.

I am trying to redirect requests to cgi-bin/java-rmi.cgi to a servlet on tomcat (from apache).
I’ve managed to redirect to the servlet successfully but I have not been able to do an implicit redirections (hiding the url change from the client).

This is mandetory since rmi will not work if it is redirected so I have to hide this from the client.

Right now my httpd.conf looks like this (only the relevant stuff obviously)

RewriteEngine on
RewriteLog logs/rewrite.log
RewriteLogLevel 9
RewriteRule ^/cgi-bin/java\-rmi\.cgi http://localhost/RMIServlet [P]

Alias /RMIServlet "C:/Program Files (x86)/Apache Software Foundation/Tomcat 6.0/webapps/RMIServlet"
<Directory "C:/Program Files (x86)/Apache Software Foundation/Tomcat 6.0/webapps/RMIServlet/">
Options Indexes FollowSymLinks
</Directory>

include "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/conf/mod_jk.conf"

additionally, my mod_jk.conf looks like this (again, only relevant stuff)

# Send everything!! to worker ajp13
JkMount / ajp13
JkMount /* ajp13

(although I presume mod_jk.conf has nothing to do with the problem)

I also enabled these:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule rewrite_module mo

dules/mod_rewrite.so

Whenever I try to open http://localhost/cgi-bin/java-rmi.cgi the page opens with the url http://localhost/RMIServlet which is not good.

What am I doing wrong?

Thanks!

    1. Dav is wrong, with [P] the replacement needs to be a qualified URI, including protocol and hostname.

    2. Is mod_proxy really active and configured correctly? Sorry, I can’t help you with that, as I have not used done this yet.

    3. Try defining RMIServlet before rewriting the URL.

    4. Perhaps there is another rewriting going on after your rule, try appending L for last rule, so make it RewriteRule ^/cgi-bin/java\-rmi\.cgi http://localhost/RMIServlet [P,L]
