CF911: Looking for info on handling IIS 7 integration in CF9 Updater 1? Not in the docs

Note: This blog post is from 2011. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.

What's changed about IIS 7 support in 9.01?

Some folks will know that ColdFusion 9 Updater 1 (9.0.1) has finally added full support for IIS 7, without need to rely upon enabling IIS 6 Compatibility (which IS still required for CF 9.0, 8.0, and 8.0.1). This is indeed great news, whether you're running on Vista, Windows 7, or Windows Server 2008, which all have IIS 7 by default, and for which you can enable IIS 6 Compatibility mode, but it's not on by default and not always straightforward to enable.

So bottom line, if you're on 9.0.1, you no longer need to go through the hoops described in the CF9 Admin/Install docs (nor in helpful blog entries like here and here, though those are still great for those running on CF 9.0 and 8, and may even offer tips of value to anyone setting up CF to run on IIS, which has other challenges on Server 2008.)

Gotcha 1: The IIS 7 Compatibility change is NOT documented where expected

Sadly, though, if you go looking for help on this in the CF docs, such as Chapter 6 of the manual, Installing ColdFusion 9, you will find that it has NOT been updated with the info that is new in the updater.

It opens, "If you are configuring IIS 7 ... ensure that you have the options IIS Metabase and IIS 6 configuration compatibility ... and ISAPI Extensions ... selected".

What a shame.

Solution 1: Where the change IS documented

So with respect to change in 9.0.1, where you no longer need to enable IIS 6 compatibility, the details are covered instead in the installation guide that was created just for installing CF9 updater 1 itself, called "Installing the Coldfusion 9 Update", available online at:

http://www.adobe.com/support/documentation/en/coldfusion/901/cf901install.pdf

It's certainly reasonable to expect that the primary install manual would have been updated with the info above.

But that's why I'm pointing this out. I have also added a comment explaining it on the page pointed to in the first link above. Hope that may help someone.

(The same info is also offered as a chapter in the manual, "ColdFusion 9 Updater 1: New Feature Notes", available at http://www.adobe.com/support/documentation/en/coldfusion/901/cf901features.pdf, which is of course very interesting if you may have missed it.)

I'll explain the second gotcha in a follow-up blog entry.
