Hey Amos, We have about 50 clients which downloads same google chrome update every 2 or 3 days means 2.4 gb. although response says vary but requested file is same and all is downloaded via apt update.
Is there any option just like ignore-no-store? I know i am asking for too much but it seems very silly on google's part that they are sending very header at a place where they shouldn't as no matter how you access those url's you are only going to get those deb files. can i hack squid source code to ignore very header ?
