No Web Connection uses zlib to compress content. IIS Dynamic Content Compression is something that happens automatically in IIS if enabled - basically it tries to compress any candidate traffic in IIS that qualifies. In general I don't like that module and keep the option disabled.
If you install IIS you do want to enable *Static* compression but not dynamic compression.

Hi all,
I was just trying to diagnose a new IIS app event (concerning static compression temp folders, but that's not my question), when I noticed a message in IIS Manager "The dynamic content compression module is not installed." This is IIS7 on Win 2008 server (64 bit).
Question is, does WWWC need this module to be installed to use its GZip capabilities? I would like to start compressing large application/JSON dynamic responses.
Thanks.
Randy
