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

Question

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.

Source Error:

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

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.

Application Pool Identities are explained pretty well in this article: learn.iis.net/page.aspx/624/application-pool-identities. There are some good reasons for Microsoft making the changes they did. – Auxesis

Restarting the application pool did it for me. Thanks! Definitely saved me some time and a sharp headache. – Schwarz

@Auxesis there is nothing wrong with fixing issues with new version but I wish microsoft would use more understandable error messages intead of very long non-sense messages – Klutz

I was having this issue hosting a .net 2.0 app on a windows 2012 server. This fixed my security issues after I registered the framework. – Glycosuria

Answer 2

Try the following:

App Pool -> Advanced Settings -> Load Users Profile = True

for me it was:
1. unblock all files http://nicholasrogoff.wordpress.com/2010/09/01/how-to-bulk-unblock-files-in-windows-7-or-server-2008/
2.restart application pool

Answer 4

One cause for this problem is when you have done the totally odd thing of publishing you application on the server by using the server to download the application from the Internet. The files will then be marked as originating from the Internet, and security settings then prevent them from running.

The "downloaded-from-Internet" mark is stored in the file system as an NTFS alternative data stream. Use the "Streams" tool to display and remove the flags: http://technet.microsoft.com/en-us/sysinternals/bb897440.aspx

Then restart the application pool.

Answer 5

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 6

I had a similar issue with GoDaddy. Even though it didn't seem related at first since it's not in the stack trace (and may not apply to you since you're using third party code), removing Response.End() calls solved the issue in my case.

Answer 7

I had this issue because of a networked drive at work.When i moved my project to my desktop it started working again.
