Hi, I want to know how Firefox implement the web prefetching(not the part on how it gets and parses the fetch hint, but the part after it parsed the fetch hint, how does it fetch the objects, and store it in cache. If it didn't finish fetching, how does it send out the request to only ask for the part it doesn't get and so on). Could any one refer to me where I should look for the source code? Thanks in advance!
