ASP.net error: "The resource cannot be found" because of a stupid "/" in IIS configuration (home directory, local path ) !

When I was testing a Web Setup project I always get a strange error (after the installation):


Server Error in '/TEST' Application.
--------------------------------------------------------------------------------
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested Url: /TEST/Index.aspx
-------------------------------------------------------------------------------
Version Information: Microsoft .NET Framework Version:1.1.4322.2032; ASP.NET Version:1.1.4322.2032


The /TEST/Index.aspx file exist in the right path on my hard disk, so I went on searching and I found out that there were several people which had the same error-problem!

I find the solution (link) :

Under the root path in IIS configuration, under "Home Directory"
under the field "local path". "c:\inetpub\mywebsite\" is not the same
as "c:\inetpub\mywebsite" apparently now. My site came back alive as
soon as I removed the trailing backslash so that the path now says
"c:\inetpub\mywebsite"!

So you see that a stupid backslash can do harm!
