Apache problem with proxy and reverseproxy


Hello

I have problem to set the right url to show in reverseproxy

Example:

ProxyPass /red/ http://11.11.1.1/school/f?p=2
ProxyPassReverse /red/ http://11.11.1.1/school/f?p=2
RewriteRule ^/red$ /red/ [R]

Request url ... is not allowed.


The problem is in f?p=2 exactly the ?


How to set url or rule

Well, I don't get exactly what you're trying to do, but I don't think you can proxy a URI like /red to a query string in the backend server.
Maybe this should do what you want:
Code:
RewriteEngine on
RewriteRule  ^/red$ http://11.11.1.1/school/f?p=2 [P,QSA]

Your idea did not work.

What I am trynig to do.

When user from outside would write in URL some IP number, then will be redirected to Proxy server (https)

MY Proxy server
Linux Suse 11
192.1.0.1


And then when I would go from outside to 88.10.1.1, then I will be redirected to 192.1.0.1 and when I would add /red/, I will come to sharepoint


And this works(only with this one I have a problem, because is ? in url and apache convert this to %3F) - http://www.asciitable.com/

ProxyPass /red/ http://11.11.1.1/school/f?p=2
ProxyPassReverse /red/ http://11.11.1.1/school/f?p=2
RewriteRule ^/red$ /red/ [R]

First of all you should ask a moderator to move this thread to the Server forum, where it will get more attention.

As I've told you I don't think this can work. mod_rewrite has the [NE] option to not convert special characters to hex, but it doesn't apply here.
You may proxy /red/ to /school/, so when a client visits http://192.168.0.1/red/f?p=2 it will get the correct url from the backend

How can I wrote that ?

Is this OK.

ProxyPass /red/ http://11.11.1.1/red/f?p=2
ProxyPassReverse /school/ http://11.11.1.1/school/f?p=2
RewriteRule ^/red$ /red/ [R]

No, I was thinking something like that:
Code:
ProxyPass /red/ http://11.11.1.1/school/
ProxyPassReverse /school/ http://11.11.1.1/school/
RewriteRule ^/red$ /red/ [R]
So whatever is passed after the /red/ URI at the proxy will be passed to /school/ at the backend

Oups I've done a mistake
Quote:
ProxyPassReverse /school/ http://11.11.1.1/school/
It should be
Code:
ProxyPassReverse /red/ http://11.11.1.1/school/
Or maybe use the same for both, like:
Code:
ProxyPass /school/ http://11.11.1.1/school/
ProxyPassReverse /school/ http://11.11.1.1/school/
RewriteRule ^/red$ /school/ [R]
The hex character for the "?" is not a utf problem. It's the way apache represents special characters in urls
Other than that I don't know what else you can do. Maybe you should google to find if it's possible to reverse proxy your application and how

You can check the logs on both apache and the backend server and see what happens.

The backend is the server you're trying to proxy (the one with the 11.11.1.1 IP)
What happens if you try to access apache on 192.168.0.1 from itself: http://192.1.0.1/school/?

I know it works. Just ask to look at the logs to see what are the actual reverse proxy requests

Isn't the 192.1.0.1 the box running apache reverse proxy?
What other proxy you say?
