Simple Cache

What's web cache

A web cache is a mentorism for the temporary storage (caching) of web documents, such as HTML pages and images, to reduce bandwidth usage, server load, and perceived lag. A web cache stores copies of documents passing through it; subsequent requests may be satisfied from the cache if certain conditions are met. Google's cache link in its search results provides a way of retrieving information from websites that have recently gone down and a way of retrieving data more quickly than by clicking the direct link.

You can easily find a snippet of code to cache your website but most of the code is not good because the programmers didn't think to issue how to let the system find a fastest cache files.

For example, you have a 1000 image files stored in a folder in your computer, when you click on that folder and you will know that you have to wait a period of time long enough for all the images are loaded off, if your computer strong enough (to spend lots of money to buy), standby time will decrease. But if your computer is too weak, the timeout too long? To fix this, you will need to split into multiple folders, and each folder contains 100 photos are downloading images will become faster and this is the advantages of Simple Cache.
