Re: [Erlangweb-users] Language support

[Graeme D. <gra...@gm...>]

Roberto,

I am not sure whether Erlang Web supports this, but one option would
be to add the current page to the language-setting URL, and then
retrieve it in the controller. i.e.something like

 <li><a href="/session/language/en?/the/current/page.html">English</a></li>

(suitable escaped, of course) and then pick it out again for the redirect.

Make any sense?
