when trying to access this thread:

the browser returns ERR_TOO_MANY_REDIRECTS.

Nor here (Chrome) or (FireFox).

Nor here (QupZilla in linux)

Ok, now it displays fine.

Before it was returning multiple 302 redirects, the console log returned 150 requests and then Chrome stopped the request, I tested few times. I have an HEAD request log:

HTTP/1.1 302 Found

If this can help. If it happens again I will try to send a screenshot.

Hmm, so strange. Yeah, the next time if it happens if you could send me the response headers (which you just did) along with the URI in the browser bar.
