Proxies aim to improve the performance offered by the Web, providing end users with faster access to its resources.
my question is like when a webpage is accessed the contents of the page remains in the proxycache. when another user requests the same page it is given to the user from the cache. in case if the contents of the page is changing every time (like some thing i buy in www.ebay.de
) in this case how it works.
any ideas welcome.
