System.Web.AspNetHostingPermission SecurityException when trying to use ManagedFusion Rewriter on Goddaddy

Question

Hello Everybody. I wonder if someone could help me out with an issue I'm experiencing trying to get my site up and running on Goddaddy. I'm trying to get extension-less url rewriting working using the ManagedFusion Rewriter (http://www.codeplex.com/urlrewriter/) Unfortunately I'm getting the following error:

Server Error in '/' Application. Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I'm runnung using IIS 7 in integrated mode. I've modified my web.config file by following the instructions in the readme file here: http://www.codeplex.com/urlrewriter/Release/ProjectReleases.aspx?ReleaseId=22618

Thank very much in advance.

Answer 1

This is actually a known issue with GoDaddy's Medium Trust environment. However with the latest release of URL Rewriter 3.0 all these issues are now gone. Please get the latest release and let me know if you have any issues.

Answer 2

I hit this same exception on a new install, changing the App pool identity to NetworkService / aspnet fixed it.

Additionally, enabling Load User Profile on the app pool also worked.

Answer 3

I had the same problem. I tried TreeUK's solution. It worked for me.

Thank you.
