Can some on help me out for this problem.
You mean zip/unzip? Please look in WmSamples or PSUtilities package there are sample services to analyze.
But is it possible to use the web server capability to compress the outgoing content. I have a similar requirement to compress my out XML so that the browser looking at my XML can decompress and show it to the user.
I believe that feature is contained in HTTP 1.1 which is not supported by IS in any current release. There was a thread that mentioned this in relation to some performance tuning recommendations from SalesForce.com a few months ago.
