trace http packet with wireshark

If I open an static webpage (don't have object to be updated) How can I identify the last http packet? Is there any properties in tcp or http that shows the last on开发者_如何学Goe?

You can filter for http packets at either the capture or display level. Then just scroll to the last packet.

If the page is dynamic what options will affect on receiving packet?For example Ajax or some other things that causes packets flow to come in wireshark and dont see no stop on packet flow.
