Spurious "/.com" inserted into URL

August 09, 2010 12:12PM
(You can see this pretty-printed at http://serverfault.com/questions/168098/nginx-just-started-inserting-spurious-coms-into-our-urls )

I made some minor changes to our nginx config on Friday (deploying SSL certs: adding a server listening on 443 with the appropriate settings and adding a couple rewrite rules to forward certain requests to it) and all of a sudden our URLs started getting extra "/.com"s inserted into them. For example, clicking a link to http://domain.com/logout/ takes the user to http://domain.com/logout/.com/. http://domain.com/register/ forwards to http://domain.com/.com/register/. This doesn't happen with a subdomain (e.g. http://production.domain.com/logout/ just works) and it also doesn't happen with https://domain.com/ (so right now, as a workaround, the entire site is being served with https).

Our nginx serves static content and proxies dynamic requests to Apache, which is pretty standard for Django. This had been working fine for months; I have no idea why it stopped working. I can't even be sure the problem is at the nginx level, but that's the only thing I changed, so that's where my attention has been.

Any help/suggestions would be greatly appreciated.

Here are the relevant config files (again, the link above has this formatted nicely):
