I beg to differ... Please re-read my statement that "...unless instructed to do otherwise..." > If it was for pure HTML only, yes, you are > correct. But with javascript you can start a timer and > execute a javascript function every once in a while. If this > javascript loads an XML document off the server, you're there ;) So you have now instructed the browser, via javascript, to periodically poll the server "every once in a while". This is exacly what the previous poster (the one I replied to) was trying to AVOID, and for good reason. It doesn't scale. In order to be effective as a way to present the user with caller-ID driven data, it would have to poll quite frequently. With a handful of clients constantly doing this, the impact is inconsequential, but as the number of clients hammering the server in this manner climbs, things are going to break. -- No virus found in this outgoing message.
