Dear, Good afternoon.

I'm having trouble using the Reverse Proxy using the Isapi Rewrite 3.

I can not open pages .asp

You could help me?

RewriteEngine on

RewriteBase /

RewriteCond %{HTTP_HOST} .* [NC]

RewriteCond %{REQUEST_URI} !-f

RewriteCond %{REQUEST_URI} !-d

RewriteRule (.*) https:// …. /$1 [NC,P]

RewriteLogLevel 9

LogLevel debug

THANKS

Please tell what error do you get, do your requested asp files really (physcally) exist?
Please provide rewrite log records for some specific request.

Guys,
I found why ASP pages were not working. We're redirecting requests from one IIS6 to another. Dynamic pages were not working because the option "Compress Application Files" was enabled in the second server. When this option was disabled, all requests worked fine.
However, I can't afford to have uncompressed connections between the servers. Is there any know issue related with compressed files through ISAPI_REWRITE 3?

We've never got any complaints about ISAPI_Rewrite not working with compression.
Please provide us a piece of rewrite log for the specific request with compression turned on.

And if possible, please show this issue online.

Anton, I work with cfcunha and I'll try to help. The compress option is enabled in the backend server. The end users receives a generic error message and the backend webserver log show the connection with status code 200.
Since we're trying to use Isapi rewrite as reverse proxy, its not an option to have compression disabled.

Do you have any way to do a online meeting?

Can you please make a direct request to your backend (without using ISAPI_Rewrite as reverse proxy) and provide us wfetch report and request
body for it.

I made the test with compression enabled in Backend and worked fine. If I make the request in the frontend, I receive the result "ERROR_INTERNET_INTERNAL_ERROR". Follow the wfetch results:

Please clarify is the above wfetch represents backend response?
Please also provide wfetch and IIS logs for the frontend.
And specify your version of ISAPI_Rewrite.
