Hi,

Quote:
RewriteCond %{HTTP} ^on$
The above is wrong. There is no such variable. I guess that's why rewrite is not working
Also, better use:
Code:
RewriteCond %{REQUEST_URI} ^/123(.*)$
to take care of the trailing slash "/"
And I don't understand the last rewrite rule after the proxy stuff.
Quote:
RewriteRule ^/123/(.*) http://192.0.1.1:88/ap/ [L,R]
After fixing the url with mod_rewrite, the proxy should take control for the rest.

Regards

Now is my configuration like this:


My proxy: 192.0.0.0 (DMZ)

My httpd.conf


AddDefaultCharset utf-8

RewriteEngine On

Options +FollowSymlinks



RewriteCond %{REQUEST_URI} ^/123/(.*)$

RewriteCond %{REQUEST_URI} !^/123/f$

RewriteRule (.*) /123/f?p=100:1 [R]



ProxyRequests Off

ProxyPass /123/ http://192.0.1.1:88/ap/

ProxyPassReverse /123/ http://192.0.1.1:88/ap/



Now i think that this RewriteCond works, but there is still a problem.


1.

When I write URL - proxy - https://192.0.0.0/123/ I become http://192.0.1.1:88/ap/ (my administrator console) -
But I wont this URL -> https://192.0.1.1:88/ap/f?p=100:1

It's look that here, where is https, RewriteCond does not work. What to change ??

My proxy has to work with https.


2.

When I write URL - proxy - http://192.0.0.0/123/ I become the right URL -> https://192.0.1.1:88/ap/f?p=100:1

But there is a problem

2.1

I become login, but it looks that something did not go true proxy.

Picture 1 - the login page when she came true proxy.
Picture 2 - the login page from application

Where is here problem.


Thanks for your time

I don't understand what you mean. If a request is done through https then it cannot be turned in http without a rewrite action from you, that is not happening here!
Anyway, why don't you use https in the proxied url?

I've already told you to remove the trailing slash exactly for this reason

Huh, maybe you need ProxyPreserveHost On. This depends mostly on the backend application.

You may try this:
Code:
RewriteCond %{REQUEST_URI} ^/123(.*)$
RewriteCond %{REQUEST_URI} !^/123/f$
RewriteRule (.*) /123/f?p=100:1 [R]

ProxyPreserveHost On
ProxyRequests Off
ProxyPass /123/ https://192.0.1.1:88/ap/
ProxyPassReverse /123/ https://192.0.1.1:88/ap/

Because application does not work on https

Where I have to remove slash ??
How comes it doesn't work on https when you say

If you want the initial request to be in https then before the other rewrite stuff, add:
Code:
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI}
About the trailing slash. Remove this (in red):
Code:
RewriteCond %{REQUEST_URI} ^/123/(.*)$
I hope that it's clear now!

My mistake when writting - -> http://192.0.1.1:88/ap/f?p=100:1


Quote:
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI}
Ok this work and convert http to https



Quote:
RewriteCond %{REQUEST_URI} ^/123/(.*)$
That only means url with http://192.0.0.0/123/ or without http://192.0.0.0/123


Any idea about problem


I canlogin, but it looks that something did not go true proxy.

Picture 1 - the login page when she came true proxy.
Picture 2 - the login page from application

Where is here problem.

If you want both (with or without the /) to work, use my rewrite rule: REMOVE THE SLASH!!!
You should read mod_rewrite documentation and especially the use of regexes.

So, anything else works except the images in the login page?
Check the logs in both apache and the backend server and see why is this happening.

If It was so, then would be OK. I only become the login page. But login does not work. No response from button (LOGIN) and so on.

It looks that I only become true proxy html page, without connection ...
