"User CP" calguns link doesn't work when using https anymore

[bool1tholz]

This started happening yesterday or the day before the User CP link doesn't work anymore.

EDIT: Mystery solved. After posting I already see how to fix/workaround it. I just cleared my cache and it works again. I noticed the "Status Code:301 Moved Permanently (from disk cache)" so the cache pragma was caching the error page in my browser. So I guess the real issue is that the pragma for the redirected error page should be set to no-cache on the apache server.

If I click "User CP" (https://www.calguns.net/calgunforum/usercp.php)

I get redirected to a generic error page.


Some diagnostic info:

Looks an apache server is being used as a gateway in front of the calguns server and the proxy directives/rules it was updated with broke user cp when used from https.

It would be nice if this worked again.
