blocking downloads on HTTPS
been racking my brains trying to figure out how to let people access things like emails on https which is great no problem but how do I stop people from downloading files from https sites ??
I am currently running the latest version of Zentyal, which is built on Squid and Dansguardian.

Everything is 'downloading files' - the best you can do is limit by size or extension, in https you'll need to be doing mitm interception.

How about blocking all https traffic apart from allowed sites? Yes it will create a small amount of admin work, but on the plus side you will have safe internet access for students by blocking all https proxy avoidance sites.

That's one (slightly brutal - cert checking has low intrusion and decent effectiveness) way of acting against https anonymisers... think the OP is after control of what happens on an individual site (like hotmail) tho - which will require full MITM.
