Just a quick reminder, as I keep coming across this one on customer sites and in the forums.
Quickr (and Sametime for that matter) is not supported with Internet Site documents.
Don't try it - it will not work! You need to set the HTTP task to use the Domino Web Configuration/HTTP settings from the server document for the server instead.
This is currently a fact of life, and you need to work around the limitation. If this is a problem in your environment, then please tell IBM...
