Enabling REST (GET, POST, PUT, DELETE) support in iis 6
Solution 1:
I discovered the answer by accident, trying to enable parent paths.
Open the IIS Management console,
Right click on your website in the sidebar and go to properties.
Go to the "Home Directory" Tab
In the "applications settings", click on the "configuration" button
In the "Applications configuration" Window, there should be a Mappings Tab
Simply choose which file extensions you want to have mapped (in my case i wanted ASP to map GET, PUT, POST & DELETE), comma delimited. And thats it, not even a restart required.
