Pass FlashVars to ColdFusion page

Hi,

Is there a way to pass FlashVars values from a .swf file to a ColdFusion page ?

I've got a page with a calendar, I select a date and post it to itself.
I then pass it into the .swf using FlashVars.

I now need to pass the date to another coldfusion page which creates xml output based on this date which will then be loaded back into the .swf, populating it with the newly created xml.

Is this possible or what would be the best say to approach this.

Many thanks in advance
