Need help with filters

Question

User-936241996 posted

I am having problems with II Filters. I had permission problems with IIS, but after uninstalling and reinstalling IIS, my extension apps run fine, My filter app starts fine, GetFilterVersion() is called with no issues. The same with TerminateFilter() when I stop the site. But I cannot get HttpFilterProc() to be called, not matter what is passed in GetFilerVersion(), HttpFilterProc does not execute. Is there anyone who can be of assistance? I am willing to pay for your time. I'd rather not reinstall IIS again, as I have Visual Studio running as well,

Hi  richalegeni,

Did you get any first chance exception when you run that method in your IIS? It is recommended to run debug tool to capture a crash dump. 

If it is making huge business impact, please try to open a support ticket and involve professional IIS support engineer.

Of course, if you have already have business contract with Microsoft, you can also involve Microsoft escalation engineer directly.

No exceptions. No errors in logs, no failed requests. Just HttpFilterProc() is never called. Can you tell me what value should be passed in to dwFlags in GetFilterVersion() to maximize the chance to call HttpFilterProc()?

I was able to figure this out. The alignment on the Structure HTTP_FILTER_VERSION was 1, and it needed to be 4.
