Apache 101 - Cache Control
Continuing with my Apache series, I'll be today talking about cache control.
According to Wikipedia, the definition for cache is:
"a collection of data duplicating original values stored elsewhere or computed earlier, where the original data is expensive to fetch (owing to longer access time) or to compute, compared to the cost of reading the cache. In other words, a cache is a temporary storage area where frequently accessed data can be stored for rapid access. Once the data is stored in the cache, it can be used in the future by accessing the cached copy rather than re-fetching or recomputing the original data."
We are going to be using two different modules here mod_expires and mod_headers. They handle cache control through http headers sent from the webserver.
