CCNA, CCNP, MCSA, CCNA Final Exam, All Answer Test Module With 100/100

I'm about to deploy a mediumsized site powered by Django. I have a dedicated Ubuntu Server.

Should I use a local copy of jquery, or should I link to a copy provided by Google or Microsoft? I'm primarily concerned about speed. I've heard that just pulling content from other domains can have performance advantages related to how browsers limit connections. In particular, has anyone benchmarked the speed and latency of Google vs. Microsoft vs. local?

I am wanting to move my website online and my website is not working on my shared hosting account, only to find out that module mod_rewrite was not loaded. I ran phpinfo ( http://imranbukhsh.com/f/fcrawl/tmp/phpinfo.php ) and I cannot see the whole section on 'loaded modules' which I can see on my personal computer after I installed XAMPP: its a huge section on my pc ( in phpinfo ) and totally missing on my shared hosting server. My hosting company is Valcato Thanking you
