Content filter on office connect router

[dmgs2]

Hi, I'm hoping someone can help me with this. I have an office connect with content filter setup on a site. We have sites like facebook blocked. someone has figured out if they use https instead of http they can basically get to any site. Even if I block the word facebook they can still get on. Any ideas? is it even possible or is it just a flaw?

Thanks

in https communication, the content is encrypted!

This is basicaly "man in the middle" traffic monitoring.
I assume the officeconnect cannot do this.
You'll need an advanced (IPS) device to do "deep inspection" of https encrypted communications.
