Is there a 3G router with local caching?

Question

I would like to have a 3G router (with WiFi) that performs local caching.

For example, when I download the same .flv movie twice, it would be cached in the router. This should be a workaround for the problem that many handhelds don't have a big cache themselves.

Is there such a thing or are there better solutions for caching?

Answer 1

It's called a caching proxy server. For HTTP, two examples are Polipo and Squid.

You can install such a proxy on your own computer, or on a server if you have one, then configure your mobile devices to use that proxy. (You could install it on the router, but it would be practically useless, as most routers have tiny storage devices. Your computer's terabyte disk is much better for caching.)
