ColdFusion page loading message problem

I need a page loading message that displays as soon as a page is called, must be a .cfm (ColdFusion page), create a page just with this in it <cfhttp url="[login to view URL]" method="GET"></cfhttp> That cfhttp will take about 15 seconds to send the results, however the page you have created (.cfm) must display the page loading message as soon as the request is made, as soon as the above page completes display the #cfhttp.filecontent# and remove the page loading message.
