Microsoft Developer Security MVP, Barry Dorrans has been busy preparing content for his Wrox Press book and in doing so has developed a Cross Site Request Forgery HTTP Module.
AntiCSRF slots into your web application and takes the worries away. The module automatically takes care of token generation and checking for every page on your web site, assuming it inherits from System.Web.Page and contains an ASP.NET form.
It’s worth reading Barry’s original announcement/blog post, it has some further information.
