Assigned to API Support #1114. As reported in Tender:

Hi,

I'm sorry, but i have to start the discussion about this post again:
http://help.themoviedb.org/discussions/problems/647-language-parame...

I just realized again how negative the effect to my application is (and your servers).

I'm trying to create an app, which always displays the right information based on the country of the user (just as your website).

Always when a search-like function is used (Like text-search, upcoming releases and stuff) i would have to make an extra request for every search-result, just to get the right release-date. - I'd like to display or sort by the release-date directly when viewing the "search results".

Wouldn't it be possible to add some extra fields in the response to add the country-dependent information like the releasedate? This could be added when the parameter for the country is given.
