// test bug 1312782.
//
// Summary:
// Assume we have 6 http requests in queue, 4 are from the focused window and
// the other 2 are from the non-focused window. We want to test that the server
// should receive 4 requests from the focused window first and then receive the
// rest 2 requests.
//
// Test step:
// 1. Create 6 dummy http requests. Server would not process responses until get
// all 6 requests.
// 2. Once server receive 6 dummy requests, create 4 http requests with the focused
// window id and 2 requests with non-focused window id. Note that the requets's
// id is a serial number starting from the focused window id.
// 3. Server starts to process the 6 dummy http requests, so the client can start to
// process the pending queue. Server will queue those http requests again and wait
// until get all 6 requests.
// 4. When the server receive all 6 requests, starts to check that the request ids of
// the first 4 requests in the queue should be all less than focused window id
// plus 4. Also, the request ids of the rest requests should be less than non-focused
// window id + 2.
