enable gzip compression on Plesk 9.2.1 and IIS 6

[theoggy]

Hi everyone,

I have a small problem.
I would like to enable gzip compression on my website, so I activate it an the IIS 6 properties.
But it doesn't worked.

My Hoster told me that this is a Plesk problem, is that right and how can I fix it?

thanks all, regards
Tobi
