WOW! That's lightning fast replies.. Thanks very much, both Ralph & Steve(felgall).
@Ralph: Well, I do agree that its a bit of an overkill for a blog and for a simple xml template. But people using external style sheets isn't uncommon.. In fact, it is used all the time for large sites, except for the fact that they combine CSS files into as few HTTP requests as possible to cut down on RTT(round trip times). Thanks for your time, however, I fully appreciate it..
@Steve Chapman: WOW! I cudn't run into a better online guru than you.. Felgall, I'm humbled, Touchwood! (am I a flatterer?). But I understand that you are a About.com guide and I hold you in awe!
Coming back to our thread, yep, I'm indeed aware of DNS look ups & RTT.
I only opened this thread to know better about the "Browser caching" principle and how it enables us to cut down on load times. I read somewhere on the net that ppl online could be so impatient that they leave your site if it doesn't load within 7 secs.
I really appreciate and look forward to your reply. Thanks Steve, Your fan base has now gone up by 1 more..
and yes, how did you like my cricket blog( I still have to do heck lotta work on it though)? Do you like cricket?
Until next time.. Cheers!
