[users@httpd] RewriteRule with [P] Flag
Dear all,
since quite some time every now and then (can i say that ;) )
i get stuck with a rewriting issue.
i would like to use the rewrite capabilities with the
proxy flag.
Example:
RewriteEngine on
RewriteRule ^(.*)$ http://localhost:9090/index.jsp [P]
Assume the server configured with the above example is
reachable via https://inthewild.org.
A request to https://inthewild.org gets forwarded all right to
http://localhost:9090/index.jsp. The server on localhost:9090
itself does a http 302 (redirect) to
http://localhost:9090/setup/login.jsp and returns that to
the browser.
The browser ends up with a not working URL:
http://localhost:9090/setup/login.jsp
I would like getting back URL's like this one:
https://inthewild.org/setup/login.jsp
Please point me to the right direction.
Thx, Axel

Thank you. Yes that works. I was hoping to avoid setting
a base URL for more flexibility.

What you need to do is look at the configuration of whatever it is you
use on port 9090. You must configure that piece of software to issue
redirects that use the right hostname. Often there is a "base url" or
"base hostname" or something similar that you can set in your config.
When running an application server behing a reverse proxy (a very
common scenario) you should configure the application server as if it
was running without a reverse proxy, as if it was the front end
server. If you can't do that there are workarounds in volving
proxypassrevers or even mod_proxy_html, but these are complicated. Try
solving the problem at the source first.

I'm just going by the manual. They weren't implemented to be used in
that context, since a normal proxy request is never mapped to the
filesystem.
Proxy works over several hooks, and suppresses ever mapping anything
to disk. In the case of rewrite in per-directory context, rewrite
kicks off the "latter" processing but bootstraps it a different way
(long after the resource has already been mapped to disk)

Eric - what makes [P] valid in an htaccess, but not
ProxyPass/ProxyPassReverse ?

Maybe 'Header edit Location ...' but I'm not sure if Header directives
in your htaccess will still be applicable after all the proxying work
is done (it wouldn't with ProxyPass, but it might since you had
mod_rewrite in htaccess)

I did not mention in this case it is about a full managed
Linux box. Access to the Apache config is not permitted.
One hat to use a .htaccess file.
Is there something similar to ProxyPassReverse which works
in the .htaccess?
