Iis – Enabling gzip compression in IIS and having it take effect

gzipiisiis-6

We've enabled Gzip compression on the server in IIS (IIS6). We've run iisreset. It just doesn't want to take effect. We had this before on another server, and after a little while, it just started working.

Is it supposed to "take" right away? If not, how long does it take? Is there anything that we can do to expedite this?

Are you sure the result's not being cached? You can verify the server remotely here

How much memory is available when you get that error? If you've saturated all memory, new sessions will fail.

IIS Compression: Enable GZIP and DEFLATE using Powershell

Your initial line of attack with PowerShell is to use WMI. Unfortunately, the root\MicrosoftIisV2 namespace is set up with non-standard security settings which you can't change in PS (not in V1, at least, V2 may be different).

I would suggest looking at the IIS ADSI provider, specifically the IIsCompressionScheme object - http://msdn.microsoft.com/en-us/library/ms524574.aspx

You may be able to work with this in PowerShell by manipulating

$obj = [ADSI]"IIS://MachineName/W3SVC/Filters/Compression/Scheme"

However, ADSI is pretty evil, so you'll have a fairly steep learning curve.
