On the Request object, there's a UserLanguages array.  It's an array of language codes as strings.  Is this what you want?

Thanks for the reply, but unfortunately the only UserLanguage strings always seems to return en-gb and en;q=0.5 (assuming System.Web.HttpRequest object... This is regardless of which language I go to (e,g, "/" [root], Russian [ru-ru] or english [en-gb].

I would have expected some sort of server session token that stores which language the last page request by the user was, and not have to send this with every request (in this particular instance I'm writing an image http handler and so it is definately not possible).

thanks

If you are doing the work in a handler then you will need to revert to some URL parsing and using the EPiServer language manager to look up the language. Something like this will do the trick:

UriBuilder builder = new UriBuilder("http://www.fullurl.com/en/content/");
string langSegment = builder.Uri.Segments[1].TrimEnd("/".ToCharArray());
LanguageNode node = LanguageManager.Instance.GetLanguages().Where(lang => lang.Name == langSegment).ToList()[0];

Ps since you are using this for an image handler you could always pass the current URL on the querystring to the handler and use the code I supplied above.

Thanks for the info and code snippet David. I was messing around with something similar yesterday.

I'm not sure I can pass the URL on the handler unfortunately (at least I'm not sure how). I've set up a httpHandler in web.config for all files in my "images/global" folder.

The idea was that any image in the folder would get served through the handler. That way I could use the same CSS and markup for all my sites, since it is only the images with hardcoded text that change for each locale. My folder structure would comprise of something like "images/global/en-gb/image.png", "images/global/es-es/image.png" etc etc. A request for "images/global/image.png" would use the current session locale to serve the correct image. If that folder was not present then I could use the fallback language (set up in episerver) to serve that instead.

I think I may just store the locale in session from my base/master page and continue that way.

thanks
