301 redirect for site hosted at github?

Question

Here's a Github repository of mine: https://github.com/n1k0/casperjs

There's a gh-pages branch to hold the project documentation, which is basically the project website: https://github.com/n1k0/casperjs/tree/gh-pages

This branch setups the documentation site at http://n1k0.github.com/casperjs/ — hurray.

In the meanwhile, I've bough the casperjs.org domain to get this website available through it, so I put a CNAME file as recommended in the docs: https://github.com/n1k0/casperjs/blob/gh-pages/CNAME — in their example, the operation is supposed to create redirects from www.example.com and charlie.github.com to example.com…

While the website now points to http://casperjs.org/, there's no 301 redirect from http://n1k0.github.com/casperjs/ (the old site url) to the new domain name.

Any idea how to setup such a redirect, if it's even possible? Is it a bug? If it is, where should I open an issue?

Answer 1

Bringing this topic back from the dead to mention that GH now supports redirect-from's redirect-to parameter https://github.com/jekyll/jekyll-redirect-from#redirect-to

Simply add this to your _config.yml

gems:   - jekyll-redirect-from 

And this to the top of your index page.

--- redirect_to: "http://example.com" ---

To avoid the duplicate content, in a first time you can add a meta canonical like this:

<link rel="canonical" href="http://casperjs.org">
