Caching on HTTP instead of HTTPS

Hi, we use your plugin by default everywhere for our clients, we always using full SSL.

Now we had a problem, we had to implement iframes under HTTP one site.

Now we see that your cache works back just over HTTP coz wordpress main setting must be enabled as “https://site.com” instead of “https://site.com”.

But we can’t change this, coz then HTTP iframe pages wouldn’t work.

So do u have any fix for this ? or will we need to implement a different cache plugin?

Thanks ??
