Step 5: Coldfusion Extensions

This last step only applies is you are running coldfusion. In the code above is a line labelled "HcScriptFileExtensions" which lists 6 extension types dealing with asp, php etc. In order to run compression on coldfusion files add the following extensions to the list, "cfml, cfm".

            HcScriptFileExtensions="aspx
                  asmx
                  asbx
                  ashx
                  axd
                  php
                  cfm
                  cfml"

Step 6: Restart IIS

Repeat the steps outlined in step 2, only this time select start. Once IIS is restarted check one of the hosted site using the compression checker utility mention in step 1.

Thats it, you should now be sending gzip compressed web pages.
