Enable GZIP compression on IIS 7.5

[javii]

Hi, I'm having trouble enabling GZIP compression on IIS 7.5. I checked it is enabled on IIS Admin at server level and application level but I cannot see gzip enabled on headers accessing a 72kb .js file:

(Status-Line) HTTP/1.1 304 Not Modified
Accept-Ranges bytes
Date Tue, 28 Feb 2012 10:34:00 GMT
ETag "8272c720e4bbcc1:0"
Last-Modified Fri, 16 Dec 2011 11:16:16 GMT
Server Microsoft-IIS/7.5
X-Powered-By ASP.NET
X-Powered-By-Plesk PleskWin

Any idea?
Best regards

Hi,

Check this documentation:
http://www.iis.net/ConfigReference/system.webServer/httpCompression

Hi Marco, I've followed the documentation you posted above and tested my site with a gzip checker(http://www.giftofspeed.com/gzip-test/) but I can't get it to work. I've been struggling to get gzip to work for a good 5-6 hours now but no luck. Is there another way to enable gzip? Thanks

Hi,

Did you also add the following to your web.config?
<urlCompression doDynamicCompression="true" doStaticCompression="true" dynamicCompressionBeforeCache="true"/>

Thank you! That did the trick
