Accessing .NET Web Service securely from Flex 3

Question

We can successfully consume a .NET 2.0 web service from a Flex/AS3 application. Aside from SSL, how else can we make the security more robust (i.e., authentication)?

Answer 1

You can leverage ASP.Net's built in session management by decorating your webmethods with

<EnableSession()>

Then, inside your method, you can check that the user still has a valid session.
