Anybody know what impact .NET will have on the writing of ISAPI filters to use with Proxy or with ISA. Because there is a common runtime is it now possible to write filters using VB.NET, C# - any pointers, suggestions, ideas, examples would be greatly appreciated.<BR>Thanks<BR>This article might get you started: http://www.asptoday.com/articles/20010126.htm<BR><BR>DuncThanks Duncan. Saw that already. Its a useful article for providing application level filtering but for developing asapi filters themselves. I have managed to get an answer from Microsoft themselves and they say:<BR><BR>"no you cannot directly do this since we provide no way to expose unmanaged entry points (dll exports) from C# or from VB. You could write a simple forwarding wrapper in MC++ that then allows you to implement ISAPI filters, and then you get to the Interop overhead issues...<BR>Don't forget that every single request goes trough every installed filter. The null path trough a filter DLL should be as close to free as possible and it certainly isn't if you need to marshal all the stuff you potentially need access to in the filter.<BR> <BR>
