You could say the internet is just full of hoarders… but in a good way. If you have been on the internet at all (which we’re guessing is a yes) you have probably heard the word ‘Cache’ or ‘Cashing’ thrown around. But what does it mean, how is it used and why should digital marketers care? Here is the ‘What’, ‘How’, and ‘Why’ behind ‘Cache’ or ‘Cashing’.
A web cache is a mechanism for the temporary storage (caching) of web documents, such as HTML pages and images, to reduce bandwidth usage, server load, and perceived lag. While temporary storage
A web cache stores copies of documents passing through it; subsequent requests may be satisfied from the cache if certain conditions are met.
There are two main reasons that web caches are used: Reduce time delay Because your computer has a version of the site already stored, it takes less time for it to get the representation and display it. Reduce network traffic Because representations are reused, it reduces the amount of bandwidth used by a client. This saves money if the client is paying for traffic, and keeps their bandwidth requirements lower and more manageable.
