Github pages: proxies and redirectsJul 2013
When I wanted to start a github pages blog, github was serving it's page requests on
These days, they service it on
<username>.github.io, probably for security reasons (session cookies?).
Anyway, when I wanted my page to be at
igor.moomers.org, my own domain name.
I also wanted the same thing under
igor.monksofcool.org, which is another domain name that is also my OpenID.
So, I configured apache to just proxy my domains to the github page.
Here is my config:
ProxyPass / http://igor47.github.com/
ProxyPassReverse / http://igor47.github.com/
This change made my openid inaccessible.
I had my openid settings in my head.
However, when I would sign in to my openid, stackoverflow would ask me if I wanted to create a new account for
In fact, I realized that even though I was proxying, I would get redirected to
github.io in my browser.
Looks like the github web server only accepts requests on one hostname. You can tell it's just one because they say so here. So, I figured I could fix my problem by setting a custom cname page. I tried that, here.
This resulted in strange behavior.
Even going to
igor.monksofcool.org in my browser resulted in an infinite 301 redirect loop to
This finally made me realize what was happening.
I was proxying all requests to
github.com and should have been using
Even requests to
igor.monksofcool.org would go to
igor47.github.com, which is NOT the domain name in my CNAME file.
Github would redirect away, and hitting that domain would again issue an improper sub-request.
To fix the problem, I removed my CNAME file and fixed my apache config to go to proxy to
Suddenly, everything was magically working again!
