How to dynamically change CSS elements to be HTTPS or HTTP

Question

I have CSS with background-image's elements that refer to another site. Problem is, that in IE you can't have resources if you are in HTTP while they are in HTTPS and vise versa.

I am using ASP.NET and I want to find a way of letting the CSS know about if it was requested in HTTPS or NOT...

And I MUST use absolute... (its on a different site)

Thanks!

Just omit the protocol (http: or https:) in your URLs: //domain/path/image.png will use the same protocol as the current page.
