Apps require webpage authentication (Spotify wont connect)

[user-removed]

Due to our company internet rules, every seperate web browser or application that requires web access must first go through a simple webpage sign on. After then unrestricted internet is given.

Spotify desktop app (Windows 7) obviously fails to connect to internet, as it has not gone through the webpage authentication. Is there any workaround for this or am I stuck to using the online web browser player...?

Thanks
