So, this means with HTTP 1.1 its no longer stateless in that sense as browser does keep some form of "connection".

Laura in her WCNA , book mentioned the same technique, I have to find out which version of HTTP was her example written for.

I have workaround it like manually, as the wireshark is "ON" i keep a look on website page, as soon it loaded (which i check load-status icon at end of address bar) I close wireshark, then i see more accurate results.

But then I see that for complete page-load up perhaps the main index page is visible but at background there are other content e.g css,.theme files that are being downloaded from external sources (that are not visible on UI itself).

So, logically is it "ok" to close the wireshark as soon as the browser ended up loading the page. Thanks.

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.

Hello,

I'm using wireshark to calculate the page load up time for a website. I'm comparing the results from other online tools such as "http://www.webpagetest.org" and see the results don't tally.

My capture filters is:

"dst host 1.1.1.1 or src host 1.1.1.1"

Further, my capture filter is

"!(tcp.flags.reset == 1) && !(tcp.flags.fin == 1)"

I'm looking at page load up time through the following UI "statistics -> summary" and time between first and last packet.

Differences in coming in seconds not ms between online test and wireshark test done from my computer. I'm using wireless NIC card.

Is there a way to tweak the param's on wireshark to bring more close to real results.

regards

asad
