Questions about delete cache

Hey there.

Why delete cache before playback?

Why does that make a difference?

Thanks

Good question, happy to help MGilles.

The main thing to remember is that when the browser encounters the need to download a page -- that is, a URL -- the first thing it does is make sure it needs to do it at all.

Because, in most cases, based on normal browsing patterns. a page you ask for probably is one that you already asked form earlier.

Rather than download every page fresh every time, the browser stores recent pages in a local cache.

This saves a lot of work, reduces the bandwidth requirement on your machine, and makes the response time faster!

It is a neat browser trick!

But, if you are testing a web page for download speed, for example, you probably do NOT want to measure how fast your machine runs, but instead you want to measure how fast the server can deliver a page.

So, to get an accurate measurement you need to delete that page from the cache before you run the testing.

Here is how the cache manager works in eValid:
