IE PrintTemplate mixed context warning

I use the IE PrintTemplate to add custom page header/footer. The print template sample I found in Beyond Print Preview: Print Customization for Internet Explorer 5.5. But over SSL when the bowser renders following tag

<IE:LAYOUTRECT ID='layoutrect1' CONTENTSRC='document' ONLAYOUTCOMPLETE='OnRectComplete()' NEXTRECT='layoutrect2' CLASS='lorstyle'/>

The mixed context warning appers:

This page contains both secure and nonsecure items. Do you want to display the nonsecure items?

When I changed The context CONTENTSRC to direct URL the warning message disappeared. But the other strange issues are arisen.

<IE:LAYOUTRECT ID='layoutrect1' CONTENTSRC='https://..' ONLAYOUTCOMPLETE='OnRectComplete()' NEXTRECT='layoutrect2' CLASS='lorstyle'/>

Is it possible to mark the document that the ActiveX(WebConrol2) control contains as secure(avoid the mixed conte开发者_如何学JAVAnt warning)?

Just want to share the solution I found.

The IE behavior describe in question is applicable only for Internet Explorer 7. The IE shows mixed context warning if the print template are loaded via URL (event it was transported via SSL).

If you use local print template no warning appears. So I imported print template as resource to ActiveX control and accessed it via the res protocol.
