I have a WCF service hosted on http://localhost:8080, and a web application on http://localhost:82. I have Windows 7 64-bit and IIS 7.5.
The pages in the web app makes AJAX requests to the WCF service using jQuery.
In IE, the service calls perform fine. In Firefox, I get a 405 Method Not Allowed error. The service calls that the web application makes from the ASP.NET code-behind always succeed.
Other developer's builds are having the same problem. I initially thought it had to do with cross-site security restrictions that were introduced in FF 3.5, based on this article: https://developer.mozilla.org/En/HTTP_access_control. However, after adding all the response headers I appeared to need, the problem still occurred.
I've run the aspnet_regiis.exe command, and the WCF ServiceModelReg.exe command as well.
Here is the request that Firefox makes:
