ASP.NET Custom Error Page Not Displayed for Abnormal URLs
Someone asked on Stack Overflow:
A vulnerability scanning service regularly tests our site for PCI scan compliance. It has just started trying to access URLs with abnormal formatting, such as:
http://www.mydomain.com/ShoppingCart.aspx//ErrorPage.aspx%3fid%3d2?
We have a Custom Error Page set which works for everything except this. Is there any way to force IIS to display it for this type of URL?
The Error: Runtime Error - An application error occurred on the server…
We’re using:
- ASP.NET 2.0 (Framework 3.5)
- IIS 7.0 (Windows Server Web 2008)
I’ve tried to debug this, but I can’t reproduce this on IIS 6.0.
I posted the following answer, which was chosen as the accepted answer and received 1 upvote:
There might be a more simple solution, but if you’re on IIS7 you can use URL Rewrite to match those type of URLs and map them back to your error page.
