q) your browser downloaded the two images from two sequential way web site, or in parallel? Explains.View your User-Agent HTTP request, use the browser is Netscape Navigator 7.01. Two images are downloaded via two different TCP connection: 4308-> 80 and 4309-> 80. Use the tcp.flags.syn filter = = 1, to observe the exact moment two TCP connections formed: 4308-> 80 > 80 at 7.284335 and at 7.285795, 4309-the difference in very little time but still found the two connections are formed sequentially. RTT of stage three-step handshake of two TCP connections vary, so we see two packages containing the HTTP response time is much different.
