//
// Summary:
// Assume we have 6 http requests in queue, 3 are from the focused window with
// normal priority and the other 3 are from the non-focused window with the
// highest priority.
// We want to test that when "network.http.active_tab_priority" is false,
// the server should receive 3 requests with the highest priority first
// and then receive the rest 3 requests.
//
// Test step:
// 1. Create 6 dummy http requests. Server would not process responses until told
// all 6 requests.
// 2. Once server receive 6 dummy requests, create 3 http requests with the focused
// window id and normal priority and 3 requests with non-focused window id and
// the highrst priority.
// Note that the requets's id is set to its 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, we want to check if 3 requests with higher
// priority are sent before others.
// First, we check that if the request id of the first 3 requests in the queue is
// equal to non focused window id.
// Second, we check if the request id of the rest requests is equal to focused
// window id.
