+// 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.
