I’m not very familiar with the newer configuration screens in Windows Server 2008 so I pulled my hair out trying to update some settings. Apparently it’s just too obvious for Google to have been any help so I’m documenting it here for the next shmuck.

I wanted to enable dynamic http compression. I found the page to enable it but it wasn’t installed:

“The dynamic content compression module is not installed.” (but we won’t tell you how to install it)

It turns out that installing it is very easy and didn’t require a reboot (for me, at least):

Install it:

  1. Open server manager
  2. Roles > Web Server (IIS)
  3. Role Services (scroll down) > Add Role Services
  4. Add desired role (Web Server > Performance > Dynamic Content Compression)
  5. Next, Install, Wait…Done!

Enable it:

  1. Open server manager
  2. Roles > Web Server (IIS) > Internet Information Services (IIS) Manager
  3. Next pane: Sites > Default Web Site > Your Web Site
  4. Main pane: IIS > Compression

You might be wondering why you’d want to compress content in the first place. This site has a nice analysis of the practice as well as detailed information regarding what compression level you should use (and how to set it).

@Anonymous(2): oh don’t worry, it’s riveting.

@Patrick: Work and babies, I guess. And “The Wire”.

Thanks for screen by screen process. It was pretty easy in windows 2003 even.

Thanks, it came in handy!

Thanks man, you rock. A little confused how Enable Dynamic Content Compression is checked and grayed out. An info bubble in Alerts tells me the Role is not installed. So does this mean IIS has been trying to compress content but it had no means how to do it?

thanks heaps - helped solve a nasty problem. After our server reboot Dynamic compression was enabled for the web site but not installed as a feature! Installing it and turning off/on fixed one problem. Now for the next hurdle :-)
