CustomErrors only catches explicit page links

Question

I have custom errors turned on and when I go to

www.mywebsite.com/video/default.aspx it shows error which corresponds to 404 and this is fine

but when I go to www.mywebsite.com/video/ it shows a generic iis 404 error.

My other pages that have files work fine like www.mywebsite.com/photo/ would redirect to www.mywebsite.com/photo/default.aspx because files exists and default is setup in IIS.

Please help. Thanks!

Answer 1

The 404 handler specified in the web.config only works for files handled by the ASP.NET runtime. This is why it is working for www.mywebsite.com/video/default.aspx and not www.mywebsite.com/video/, the generic error your observing is the one configured by default in IIS. You will need to go into IIS Manager and set 404's to be redirected to your PageNotFound.aspx.
