XF 1.1 Trailing slash causing redirect loop

[Chris D]

I have a desire to enable full friendly URLs on my site.

This is working great on my dev site, where I cannot replicate this error.

But I am experiencing an odd redirect loop. The error can be reproduced with, or without the full friendly URL function enabled.

It is currently disabled, yet if I go to http://www.valvetime.net/forum Xenforo redirects me correctly to http://www.valvetime.net/index.php?forum.

If I add a trailing slash and go to http://www.valvetime.net/forum/ then I experience the error. I am incorrectly redirected to http://www.valvetime.net/forum/index.php?forum/

To make things more sinister, when full friendly URLs are enabled, then URL will cause the loop, trailing slash or not.

Any idea what causes this?

Advice greatly appreciated!

however, completely clearing the browser ( cahce, cookies, history ) solves it

What browser?

I often have problems with Firefox caching redirects. I have to use Chrome to know that I'm current.
