Get redirected url from code

Question

Hey,

I'm using an API which, given a url, redirects to a file on the server. The file names have "_s,_m and _l" appended to the end (small, medium, large). However, since the url's querystring is parsed dynamically, I don't retrieve the actual file name. The image displays correctly, but is it possible to retrieve the filename of the image file from the code? (i.e. where the url has redirected to)?

e.g. http://api.somesite.com/getimage?small (this is what I enter)
"http://somesite.com/images/userimage_s.png" (this is where it redirects to. I would like to get this address from code)

Thanks for any advice

Sounds to me like you are trying to access some images you shouldn't access programmatically ;-)

You could access the given URL with an HTTP client (opening the stream with a stream reader might already suffice) and watch out for a Location header, which will most likely contain the URL you are searching for.
