We have a situation internally caused by our ISP's filter which means YouTube HTTPS content doesn't work.

While I realise this is more an issue for us internally to deal with, the YouTube filter forces all content it uses to a HTTPS url. Using the standard iframe embed url works correctly.

Looking at the embed code YouTube provides, the url omits the http/https and the embeded content picks up which ever protocol is being used. Is it possible so that the filter is modified to omit the protocol so that content doesn't create a mixed content environment, but removes the problem of being forced to use HTTPS?
