[squid-users] How does squid handle http get file splitting?

[Dave Theodore]

I have an application that does http gets of large files (>500mb) and in 
order to minimize the pain of losing a connection and having to 
reconnect, it requests 1mb file chunks and reassembles them once all 
pieces have been received.  I am hoping to use squid to reduce the load 
on the main webserver farm and eventually distribute the content 
geographically without worrying about replication issues. 

How does squid handle caching of these file chunks?  Does it fetch the 
entire file in order to serve the request for 1mb or only request the 
part of the file being requested by the client?  The client side always 
requests files in the exact same way IE chunk 1 = 1-1024, chunk 2 = 1025 
- 2048, chunk 3 - 2049 - 3072, etc. so there is value to caching the 
individual file chunks. 

Any input is greatly appreciated.
