Elixir: Redirect old docs website to hexdocs

[alex88]

After posting in the slack channel @jeregrine told me to open an issue here.
Basically all my browser history elixir docs points to the old stable url http://elixir-lang.org/docs/stable/elixir, wouldn't be possible (and useful) to redirect that to the new hexdocs website?
Because the url still shows stable but shows the old 1.3.4 version, someone that ends up there wouldn't know that there is a new stable version out there
It should be pretty straightforward as the path after stable is the same you can find in hexdocs.

There is already an open issue here: https://github.com/elixir-lang/elixir-lang.github.com/issues/921 We plan to set up redirects soon.

Thank you for reporting anyway!

Oh that's why I haven't found it, i was searching on this repo! Ops!

@alex88 could you please test it now?
and let me know if you find anything not working as expected in https://github.com/elixir-lang/docs/pull/17
thank you

Hi @eksperimental, it seems to work correctly!
Too bad it won't trigger a 301 but from a fast research seems it's not possible with github pages, so browser urls won't change probably.

[eksperimental]

yes, it is not possible with github pages, otherwise it would have save me the trouble of creating 1,500+ unique pages.

At the very least a <meta ... redirect header and fallback javascript to redirect would work for most purposes? And easy to generate 1500+ pages with some sed'ing for the urls...

@OvermindDL1 such solution has already been pushed.
