Partial object caching with varnish

[Madhava Gaikwad (madgaikw)]

Hello,
I am newbie to varnish. I want to confirm following two things I am trying to accomplish.
I understood varnish can do live streaming etc. But can it really just do partial object caching. Say if I send a range request for 10 bytes from a pdf, and setup varnish cache to cache everything, will it be able to do it? What is the VCL config I should look at this.

I have a forward proxy which cannot do range request caching. Neither it can do streaming. So I am thinking to put varnish in between client and forward proxy. Forward proxy connects to internet. I know you may come up and laugh at me first on what I am trying to achieve, but is it achievable?


Thank you.
Madhava
