jquery - ASP.NET Forms Authentication using third party javascript library -

I have a website where I am currently in ASP.NET authentication, profile and role management. I would like to transfer some functionality (including authentication) to the client, using a junk library and generated proxy classes without the use of a third party JavaScript library like JPAR or Script Manager.

There is very limited information on this subject, but I managed to find that the WCF authentication end points for use with a silverlight application

If you have any links Or information, please let me know.

Thanks

You are probably struggling to find resources for this, because it is not safe to put your authentication control over the client.

What are your reasons for doing this?
