Re: calculating page load up time using Wireshark

[T B <phreakocious () gmail com>]

This is going to be tricky, especially with HTTP 1.1 connections, as the
browser could hold the connection open after the last element has been
loaded.  It would be better to look for the last client ACK of a packet
containing data, but I don't know of an easy way to get that level of
specificity in a filter.
