How can I block or disable google cache pages?

[Eric_Speake]

We have R80.10 and I am looking to block the ability to view cached google pages. Any ideas or thoughts?

Thanks,

Eric

Note that cached pages in Google are categorized if you have the appropriate option enabled (see below)--believe it is enabled by default.

I suppose you can block access to http://webcache.googleusercontent.com/ if you want to block access to all cached content.

Thanks I added google cache and webcache.googleusercontent.com. We want to block all of the google cached sites so they slip through fw. And yes we have Application & URL filtering set to catagorize as well.

Google uses wildcard certificates.

This makes it difficult to determine which Google property you are connecting to in a secure way.

You need to do two things to truly block this:

1. Enable HTTPS Inspection

2. Block QUIC protocol
