GZIP

Today, i have been trying to get GZIP compression working for my local machine which runs IIS7 with Windows 7. For some reasons GZIP compression isnt working even though i have checked the applicationhost.config and mime type has been configured correctly.

Turn out the issues requires additional tweak.

Compression is 'locked' by default at the application level. As such, it needs to be 'unlocked'. this can be achieved via the command line or via the (extra download) iis7 admin tools.

eg. appcmd set config -section:urlCompression /doDynamicCompression:true
