Problem with port number on redirects

I am not sure if I can explain this well, but here it goes.

I am running apache 2.0.48 that uses a mod_iiop connector from Borland
to forward requests to a tomcat server.

Users enter into our system using a F5(BIG-IP) on port 80. This in
turn performs round-robin to our apache servers running on port 7080
which in turn forwards the request to tomcat on port 8080. When a jsp
running in tomcat does a redirect
the redirect ends up going to the F5 on port 7080 instead of port 80.

I have searched the mailing list and have seen similiar questions to
this, but not been able to get an answer that seems to work for me.
I can not change the port of apache to port 80(firewall reasons), and
so far UseCanonicalNames turned off and trying ProxyPassReverse did
not do the trick.

My question is do you know of a way to make this work? Or am I stuck
trying to get the mod_iiop connector from Borland to do what I need.

Thanks for any help you can give

I don't know mod_iiop but
i had the same problem with mod_jk2

That's what i did to fix the problem:

Turn "UseCanonicalName on"
append the http port to the server name "ServerName www.server.com:80"

If there is no problem with the module this should work.

otherwise it is possible to add a "proxyPort="80" into your tomcat's
server.xml this is a way when you are doing an http connect to tomcat
via ProxyPassReverse.

If all the other ways are not working it is probably a bug in the module.

here's the bug i found for mod_jk2
http://issues.apache.org/bugzilla/show_bug.cgi?id=16901

and the fix wich worked for me is at
http://issues.apache.org/bugzilla/sh...attach_id=4819

Probably it is the same kind of problem.
