My PC is running windows XP. I have been trying to capture HTTP traffic but if I apply the following filters, the Wireshark gives results not required

  1. http result: it only show ssdp traffic
  2. http (!udp) result: it does not show any thing
  3. http (!http contains ssdp) result: it does not show anything
  4. http && tcp result: it does not show anything
  5. http (!udp.dstport == 1900) result: it does not show anything
  6. tcp result: it shows tcp traffic but I cannot reach my required http messages

The same thing is happening when I run it on a different OS (Windows 7) on my laptop.

does the http server use the standard 80 port ? – LiuYan 刘研 Oct 12 '12 at 5:00
Any chance you should be expecting TLS instead? The SPDY protocol manifests as TLS. The corresponding filter is SSL – Jan Dvorak Jan 14 '13 at 18:37
