FORCE_SCRIPT_NAME causes HttpResponseRedirect to fail

[Sean Herron]

When FORCE_SCRIPT_NAME is set in settings, redirects using HttpResponseRedirect seem to fail.

Expected behavior:
While FORCE_SCRIPT_NAME is enabled (set to foo), HttpResponseRedirect should return the user to a correct path, prepended with the script name. (eg, /foo/bar).

Actual behavior:
HttpResponseRedirect doubles the script name and redirects the user to /foo/foo/bar.

As a workaround, I created a utility function to reconstruct a full URL to redirect the user to, but this should not be necessary.

from django.shortcuts import redirect
from django.core.urlresolvers import reverse
from django.conf import settings

def absolute_redirect(url, args=None):
    """
    This is a function that I needed to make because
    Django's default redirect function doesn't work properly when
    FORCE_SCRIPT_NAME is set. It returns a full URL for redirection
    """
    
    reverse_url = reverse(url, args=args)

    if settings.URL_ROOT:
        reverse_url = reverse(url, args=args)
        return redirect('%s%s' % (settings.URL_ROOT, reverse_url))
    else:
        return redirect(reverse_url)

Can you tell if you have the same problem setting the var to this:

FORCE_SCRIPT_NAME = "/foo/"

If this solved the problem the bug is related to the documentation.

P.S.
FORCE_SCRIPT_NAME replaces some server setted vars like these
​http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html#EnvVar
So it is probably expect to have the same format /foo/var/ else you could have unexpected behaviors like relative-like urls.

The problem appears to happen with any combination of FORCE_SCRIPT_NAME (foo, /foo, or /foo/). I've tested with pretty much any combination of things I could think of, even trying with the full domain name, but haven't been able to get around the issue.

Please try TicketClosingReasons/UseSupportChannels to ensure you server setup is correct and reopen if you can say more about where the bug lies or where the documentation could be improved. Thanks!
