Hi Marco,
There's not really a way to have the server tell the client to refresh the
page. However, the server can send information that tells the client to
refresh the page at a specific interval. There are a couple of ways to do
this. One way is to add a META tag to in the HEAD of the HTML sent to the
client. For instance, if you want the entire page to refresh every 2
seconds, you could add the following tag to inside the HEAD element:
<META HTTP-EQUIV="REFRESH" CONTENT=2>
You can also use client-side script to force a refresh. You could use a
combination of window.setInterval() and location.reload() to periodically
refresh the page.
window.setInterval:
http://msdn.microsoft.com/library/d...uthor/dhtml/reference/methods/setinterval.asp
location.reload:
http://msdn.microsoft.com/library/d...hop/author/dhtml/reference/methods/reload.asp
If you wanted to refresh the page only when the image is updated, I would
pursue perhaps having a hidden frame with a page that periodically checks to
see if the image has been updated since the last time it was loaded, then
refresh the entire page if it has.
Good luck!
