"any language" search setting not remembered

[osma]

At which URL did you encounter the problem?

http://finto.fi/fi/

What steps will reproduce the problem?

1. Select the vocabularies Allärs and YSA, and "any language"
2. Search for something e.g. "katt", press Enter to get the search result page
3. Click on the first result to get to the concept page
4. Click the logo to get to the front page

What is the expected output? What do you see instead?

Expected that the search language setting would be preserved, so that subsequent searches would still target all languages. Instead it changes to Finnish or Swedish on step 3 and remains so in step 4.

What browser did you use? (eg. Firefox, Chrome, Safari, Internet explorer)

Firefox, Chrome

Possible solution: Keep the anylang parameter (for global search) in a cookie, similar to how the selection of vocabularies is remembered

The problem with this implementation is that it now relies on cookies on the server side, which may mean that a different HTML response is returned for the same URL (depending on the cookie value). This is bad for caching, we have previously tried to avoid this situation. It would be better to check the cookie value in JavaScript code only and set the language selection accordingly on the client side. The server would just see the URL parameter anylang as before.
