Hi,
I am setting up a reverse proxy configuration that will proxy all
requests starting with /apps/ to a Tomcat server running on a closed
port. I have set up following configuration in httpd.conf:
ProxyRequests off
ProxyPass/apps/ http://localhost:8082/
ProxyPassReverse/apps/http://localhost:8082/
ProxyPassReverseCookiePath/apps/ /
This generally works, even for internal redirections inside the Tomcat
apps I'm addressing. Suppose my Tomcat app is internally accessible at
<http://localhost:8082/my_app/>, and this request is internally
redirected to <http://localhost:8082/my_app/index.htm>, a request for
<http://mydomain/apps/my_app/> is correctly redirected to
<http://mydomain/apps/my_app/index.htm>.
Yet, there's a webstart application inside a Tomcat app that needs the
*original* URL, instead of the proxied 'localhost:8082' URL. Hence, I
tried by adding:
ProxyPreserveHost on
But this does not work 100%:
-internal redirects inside the Tomcat app omit the /apps/ part from
the redirected URL. For example, a request for
<http://mydomain/apps/my_app/> now ends up at
<http://mydomain/my_app/index.htm>.
-also (and probably related): the webstart application inside the
Tomcat app doesn't preserve the /app/ part of the original request, and
fails.
All does work perfectly, however, with ProxyPreserveHost switched on,
when the entire URL space is proxied: "ProxyPass /
http://localhost:8082/"; etc. But I explicitly want to limit the proxying
to just one URL pattern, starting with '/apps/'. How can the '/apps/'
part of the original request be passed on to the proxied URL (as
apparently was the case with ProxyPreserveHost switched off)? (Note:
proxying to http://localhost:8082/apps/ is not an option, as there is no
physical /apps/ folder there).
I hope this sketches my problem. I have the feeling I'm almost there;
any help much appreciated!
