ASP.NET URL ending in /%20/ is not getting to application code

Question

If one has a URL like this:

https://someserver/somewebApp/%20/ ~ http exhibits the same problem.

it appears that IIS (v7.5) has a defect because control for URL evaluation does not appear to be passed to the application?

Can anyone confirm they have seen this before? Is there a Microsoft reference to the defect (I can't find one)?

To answer the comment regarding the error received - no sub code offered (at least by fiddler):

HTTP/1.1 500 Internal Server Error
Cache-Control: private
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/7.5
X-Powered-By: ASP.NET

what is the error? are you getting HTTP 500? If yes, what's the subcode? — Tony Stark, Oct 14 '14 at 16:36
You could add this to your webconfig `` `relaxedUrlToFileSystemMapping="true"`. It opens up security issues, though. — area28, Jun 30 '15 at 17:15

Generally %20 represents a space in url. so your url will be like /somewebApp/ /. this might be a problem as it is not a valid url. You can refer following link about %20
