Bandwidth

[Michael]

I have had no replies to this in the HTML/JS forum so I will try here.

If, for example, I have a web page of 10k and it includes a graphic of 20k, then when I download the page I have used 30k of bandwidth. No problem so far!

If I then load another page of 10k which includes the SAME 20k graphic, how much bandwidth will I have used to display the second page?

Will it be 30k? 10k + 20k
Will it be 10k? Because the graphic is cached
Or does it depend on the host?
Or even a browser setting?

I think you've used the wrong term here...by using 'bandwidth', you would be referring to the measure of speed of download of the files. But you are actually talking about how much data was downloaded, right?

But anyway, I think something like that is something very hard to determine. Like you said, the browser could have cached it, or if the person was using a proxy, the proxy could have cached it, or the proxy could have 1/2 of it in its cache since the last incomplete download of the file, or maybe even the file could have been downloaded by someone else using the same ISP and it could have been cached by the ISP's proxy or perhaps the person chose to use no cache!

You raised more questions than I did!!!

The term "bandwidth" seems to mean different things depending on who you are talking to, and/or the context.

Here I am referring to the situation when your web host says "you can have 1 Gb of bandwidth per month". I am trying to do some calculations about how many visitors I can get without incurring "excess bandwidth" charges.

I know it will be a while before this becomes a real problem to me but I always like to be prepared!

I replied to this post in another forum I think.
