Caching Chromebooks updates: on premise caching from non proxy-configured client?

  • 772

Before even attempting to setup something that wouldn't work, I'd like to understand if the following configuration has a logic.

Basically we want to stop Chromebooks to steal bandwidth on updates. Google suggests to setup a local web caching server so that requests to dl.google.com are cached in LAN, saving 400mb online requests per each Chromebook.

This could be done setting up a local web caching proxy (squid?) and declare this as a proxy in the Chromebook configuration, however, as I would like to limit request to the local web caching server only for dl.google.com and nothing else, I thought I could create a local DNS record on the LAN's DNS server, so that requests to dl.google.com are forwarded to the local proxy.

In your opinion, will this work, or will the proxy refuse/ignore requests from hosts that are not intrinsically configured to use a proxy?

    Thanks to Jordan Dalley, who tweaked an Nginx LanCache configuration,

    "on premises caching or micro-CDN solution for Microsoft, Google and Adobe products"

    we are now using a tiny CentOS virtualised machine, which is exclusively dedicated to local caching purposes. Caching is done transparently and working perfectly.

    Thanks Jordan for helping me!
