Cache problems when generating links with the LinkManager class

Question

I use the following block of code to generate the links of media items in a specific language:

    Sitecore.Links.UrlOptions urlOptions = Sitecore.Links.LinkManager.GetDefaultUrlOptions();
    urlOptions.AlwaysIncludeServerUrl = true;
    urlOptions.Language = Language.Parse(item.Lang);
    string lnk = Sitecore.Links.LinkManager.GetItemUrl(pdfItem, urlOptions);

...
linkfield.Url = lnk;

The link generated looks like this:

http://cd5-int.global.com/-/media/Files/Mediaroom/700767.pdf

My problem is it keeps redirecting me to the last language version i clicked on. It seems to be a cache problem because when i click the link opening my media, if the pdf opened in a new window is in the wrong language, i just need to refresh the page and then the pdf appears in the right language.

Did i miss some useful options in my urlOptions object ?

Answer 1

For media items you should use the MediaManager to generate links instead of the LinkManager. The MediaManager will return a link to the actual media item.

var urlOptions = new MediaUrlOptions();
urlOptions.Language = Language.Parse(item.Lang)                
var lnk = MediaManager.GetMediaUrl(item);

Answer 2

Try including the LanguageEmbedding option in your UrlOptions:

urlOptions.LanguageEmbedding = LanguageEmbedding.Always;

That should result in a URL that has the language in the querystring, like so:

http://cd5-int.global.com/-/media/Files/Mediaroom/700767.pdf?lang=en
