which http method is used to send data to the server?
bosh
for "push", a bosh client starts an http request, but the server postpones sending a reply until it has data to send. after receiving a reply, the client immediately makes another request on the same http connection, so the server can always send data to the client without waiting for the client to poll. if, while waiting for a reply, the client needs to send data to the server, it opens a second http connection. there are at most two http connections open at a time, one on which the server can send data as a reply and one on which the client can send data as a post.
bosh (protocol)
the effectiveness of this data exchange depends largely on the policies that clients use to determine to whom to send data. clients may prefer to send data to peers that send data back to them (a "tit for tat" exchange scheme), which encourages fair trading. but strict policies often result in suboptimal situations, such as when newly joined peers are unable to receive any data because they don't have any pieces yet to trade themselves or when two peers with a good connection between them do not exchange data simply because neither of them takes the initiative. to counter these effects, the official bittorrent client program uses a mechanism called "optimistic unchoking", whereby the client reserves a portion of its available bandwidth for sending pieces to random peers (not necessarily known good partners, so called preferred peers) in hopes of discovering even better partners and to ensure that newcomers get a chance to join the swarm.
