Subject: RE: old avatar keeps re-appearingBAMBAM66 - 2008-06-07 8:23 AM For future reference, cache is the storage of temporary internet cookies which are used to identify your computer by the sites using it. Sometimes the cookies only remember what was there and need to be cleared out for new memories to be created. Close, but not quite. Cache and cookies are both kinds of temporary storage, but they're used and managed differently. Your browser cache is sometimes referred to as 'Temporary Files'. These are local copies of pages and images stored by your browser so that it doesn't have to continuously get them from a server every time you visit a page. This speeds things up considerably.
Avatars are cached locally by your memberid and the word 'profile', so when you change the image on the BT server, your computer still sees an image in the same place with the same name so it figures "eh, nothing's changed, I'll use the version I have here in my cache rather than get it off the server". A web site has some control over what your browser should and shouldn't cache, but it's mostly controlled by the browser.
Cookies are text files with data about a particular session. A website that you visit has to have code that specifically says "write this information into a cookie with this name." To use the information it has to have code that says "read this information from this specific cookie". It's used for things like log in information, view settings etc.
