Hi Sebastian Thanks a lot for your reminding of using cache. I think your point is quite right.
However, what I did to test my script is that, each time I browse the google page, the browser is started with an *empty* cache, and meanwhile I used firebug(or other trace capture) as a test benchmark. And my problem like that can be quite often happens. btw, I also tried disabling firebug and any other firefox extensions in order to avoid some unknown in-compatibility issues. but the problem is still. thanks again for sharing your tips. regards cui 2011/12/2 Sebo <sebastianzart...@gmx.de> > Hi cui, > > I'm not the Net panel expert as Honza is, but I'd say, if you get a > connecting time of a few milliseconds, then the response comes from cache. > To stay at the Google example: If the browser cache is enabled, and you > reload the page, Firebug also displays 0ms as connecting time to me. > > Sebastian > > -- > You received this message because you are subscribed to the Google > Groups "Firebug" group. > To post to this group, send email to firebug@googlegroups.com > To unsubscribe from this group, send email to > firebug+unsubscr...@googlegroups.com > For more options, visit this group at > https://groups.google.com/forum/#!forum/firebug > -- You received this message because you are subscribed to the Google Groups "Firebug" group.
