[wp-hackers] Best way to avoid mixed http/https content

This just came up in a recent thread, I think, but I can't find it in the archive.

The gist was: 

Either filter post content to switch http:// to https:// (or vice versa) or use protocol relative urls:

Ideally you'd switch to protocol relative URLs on save_post instead on display for maximum performance (i.e. then you're only filtering the content once).

This is good, because it means that you can move the site from one place to another, and you just need to search/replace the URLs. However, that doesn't work well if the site is meant to be available via both http and https. It'll cause mixed content warnings.
