Is HttpWebRequest supposed to work in Web Builds or not?

So, I created a little mini-project to test using an HttpWebRequest object to make Facebook Graph calls on each of the Unity target platforms. I did this successfully on the following platforms: Editor, OSX Desktop, Windows Desktop, iOS.

However, I ran into a problem when trying a Web Player build. I got the follow exception when I tired to call HttpWebRequest.Create().
System.NotSupportedException: at System.Net.WebRequest.GetCreator (System.String prefix) [0x00000] in :0 at System.Net.WebRequest.Create (System.Uri requestUri) [0x00000] in :0 at System.Net.WebRequest.Create (System.String requestUriString) [0x00000] in :0 at GraphProof.ExecuteHttpWeb ()[0x00000] in :0

According to Unity Documentation at HttpWebRequest should function in the Web Player. Here is a screen capture of the line in question on the MonoCompatibility page:

Is the documentation in error, or could I be doing something wrong (keeping in mind that it worked fine on every other platform I tried).

Also, not looking for anyone to point me to alternatives, I’m aware of things like the WWW class and UniWeb. The targeting of HttpWebRequest is intentional .

The class should work, however some related classes are not supported, so it depends on how you use the webrequest. Also you can’t use it to access a third party site due to the SecuritySandbox. The webrequest is of course build on top of .NET sockets. So that would require Facebook to run a crossdomain policy server which they don’t run.

I never tried something like that, but this might help.
