A client facing web page needs to check a remote file every 2-3 seconds for image details. If the image has changed update a div on the web page, if the image data has not changed, do not update the div. The client facing web page will have several hundred people looking at it, and if each page is requesting data from the server frequently and re-downloading the image it creates a lot of requests and traffic on the server. So, I'm looking for an efficient caching or something to reduce server load and browser data. Also handle the situation if the server is slow to respond, don't send a new request, so you should use a keep alive or similar to minimise problems. Can you solve this? Your output is to create a working sample of this situation. 1) folder of images. 2) server php file randomly chooses an image file. 3) client html file checks this php file every 2-3 seconds and updates the page on first load and then again only if the data has changed. Thanks

Hi, Do you have access to the server where the image resides? About the checking, I can try to make a persistent connection or if you have access to the server, use a md5 hash of the image or even use memcache. Regards, Sergio.
