I see three options here: 1. Correct the Nginx config. This seems the obvious answer, the one on the Stack Overflow thread, and presumably you have no problem with it, since you think `web.site.com` and `web.site.com:443` are equivalent, so there's no harm dropping the `$server_port` bit. 2. Add `web.site.com:443` to `CSRF_TRUSTED_ORIGINS` ([https://code.djangoproject.com/ticket/28488#comment:39 as others have done here]). 3. **Add logic** examining the environment to infer the `443` port. I'm sure we could get 3 roughly right with some effort. But I'm equally sure that it would turn out to be wrong for someone's setup. Then we'd have to add edge-case handling and opt-outs and all the rest of it. In my view such things are **simply not worth the effort** when options 1 and 2 are available. I suggest you take one of those. > I wish there would be a way to disable referer check altogether. You could always subclass the CSRF middleware. I wouldn't do that. (I'd go with option 1.) -- Ticket URL: <https://code.djangoproject.com/ticket/30017#comment:8> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.

Anyway, this would be a workaround for this problem, not a solution. > infer the 443 but we're making assumptions in doing so Port 443 is not an assumption, but part of Internet Standard RFC-2818 https://tools.ietf.org/html/rfc2818 > the default port is 443 All browsers for example, when you type in https://abc.com "assume" same thing unless port is given, and they "assume" port 80 when you specify `http://` - because it's part of Internet Standard. > Neither the Host nor the `X-Forwarded-Host` include the scheme right? > As such it's just not right to say that `web.site.com` and `web.site.com:443` are the same. Not quite right. Django has `X-Forwarded-Proto` header and it knows that it's `https` and not `http`. That's my last attempt to reopen this ticket. Thanks for the feedback, but I believe this is a real problem in Django. Moreover, not sure why Django is making a big deal from `Referer` check? It's not a real security as `Referer` header can be easily spoofed https://security.stackexchange.com/questions/66165/does-referrer-header- checking-offer-any-real-world-security-improvement I wish there would be a way to disable referer check altogether.

Notice the error again - netlocs don't match because one has a port (443) and another doesn't have it (443 port is default for https): Referer checking failed - https://hue-dev.discover.abc.com/hue/accounts/login/?next=/ does not match https://hue-dev.discover.abc.com:443/. so I guess it should be some sort of Referer field transformation made in nginx config to cut out 443 port explicitly (or add it). Referer check is failing because django.utils.http.is_same_domain() takes into account port (in referer.netloc ). Django should assume that port 443 is default for httpS, and not fail Referer check in this case. -- Ticket URL: <https://code.djangoproject.com/ticket/30017> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
