I'm tyring to better my skills in development so i assigned myself this project. Create a dating or friend's network site.
My goal was that i'd learn how to do stored procedures and learn about all the cool functions in php.
I wanted to ask a question. I've been researching and im' learning that PEAR is a good module to use for caching information.
According to this article,
http://www.devshed.com/c/a/PHP/Output-Caching-with-PHP/3/
there are three types of caching policys...
- Time triggered caching (expiry timestamp).
- Content change triggered caching (sensitive content has changed, so cache must be updated).
- Manually triggered caching (manually inform the application that information is outdated, and force a new cache creation).
Do websites like match.com and personal.yahoo.com and others, do they use caching technologies ?
If so, what type of cahcing policy are they using ?
Is it jsut caching .. how else are they making the search functionality so speedy ?
Image preoloading through javascript ?
thanks.
