Codeigniter 2.0 CSRF Problem

[eluser]lennierb5[/eluser]
I had CSRF protection set to TRUE and ran into the following problem:

If my $config['base_url'] was set to something like "http://mydomain.com/myproject/" and I attempted to login / submit form data from the site http://www.mydomain.com/myproject/ it generates the error:

An Error Was Encountered
The action you have requested is not allowed.

The same thing happens if you try http://myip/myproject and try to submit data it seems like it must exactly match the hostname supplied in $config['base_url'].

Everything works fine if my hostname is exactly as supplied in the $config['base_url'].

Any ideas on how to fix this without turning off the CSRF protection?
