To save bandwidth and data on my Internet plan, I have installed squid-deb-proxy on a desktop, and the client on it and a few other machines I've got. However, based on the post that put me onto this , it sounds like if I take my laptop* to a different network and update it there, the downloaded updates will NOT be automatically copied back to the squid-deb-proxy server when I get back on my network.
Assuming that this is correct (I will be testing later), is there a way I can stick these packages into the cache so I don't have to download them one more time for other machines in the network?
* As noted in the comments, I could simply make the laptop the proxy server, but in my specific case, the laptop is actually 1) a VM that is not running all the time, 2) in a laptop that is not open all the time. As such, that solution, while a good one, does not work in my case.
