Hello, Regarding the very Important ASP.NET Security Vulnerability (see http://weblogs.asp.net/scottgu/archive/2010/09/18/important-asp-net-security-vulnerability.aspx), it's possibe for me (or maybe you have already install it) to check if the IIS URLScan module is installed on the IIS web server that my website is hosted? Thank you
URLScan is not installed on the server. You should implement the customError workaround http://weblogs.asp.net/scottgu/archive/2010/09/18/important-asp-net-security-vulnerability.aspx
