We created this domain to house iframed content and other things. To get the list of links, go to the OneNote page called ITSAPPS content.
We are setting up an ITSAPPS site in site improve so that we can track broken links and possibly other problems on these pages. Below is a list of the iframed pages within ITSapps. (There are a few other things hosted on this domain - for a full list see OneNote page ITSAPPS contents - but we are not concerned about monitoring these other pages)
