I'd like to use SSL on a site with many externally hosted images. I'm worried about getting warnings for the ones that are nonsecure http images. I know that one option is the image proxy, but my host has some issues with that. So I was thinking that if the hyperlinks were all converted to be protocol-relative hyperlinks (just starting with // ) then that might prevent the errors. Would it be possible to use the profanity filter or some other method to remove the beginning of links to make them all protocol relative? Would that solve the issue?
