How To Decide the Web Page is Updated or Not?
Dear all,
I am trying to implement a system that needs to access Web pages. To increase the performance, I hope to fetch Web pages only if they are updated. It seems that it is not accurate to do that based on date information of a page? If so, could you please give me an idea? What does IE deal with this issue?
Best regards,
Greatfree

why don't you make a timer to check if the html code of the page has changed?

Make a timer? The timer must reside at the client. If so, it only works after a page is transmitted to the client. Even if the page on the server is changed, how can I realize that?
