Nginx configuration leads to endless redirect loop

Question

So I\'ve looked at every sample configuration I could find and yet every time I try and view a page that requires ssl, I end up in an redirect loop. I\'m running nginx/0.8.5

Answer 1

X_FORWARDED_PROTO as in your file can cause errors and it did in my case. X-Forwarded-Proto is correct whereas the hiphens are more important than uppercase or lowercase letters.

You can avoid those problems by sticking to conventions ;)

Answer 2

I found that it was this line

 proxy_set_header  Host $http_host;

Which should be changed to

 proxy_set_header  Host $host;

According to the nginx documentation by using '$http_host you're passing the "unchanged request-header".

Answer 3

Have you tried using "X-Forwarded-Proto" instead of X_FORWARDED_PROTO?

I've run into a problem with this header before, it wasn't causing redirects, but changing this header fixed it for me.
