hmm... in that case perhaps the open connection could be employed and the feature used selectively; only on certain pages for instance ? im thinking mainly of a monitoring page; like an app that shows a servers state, or stock quotes or something. the main reason i dont like a javascript timer refreshing the page is sometimes you dont want the whole page refreshed; especially when halfway through filling out a form on the page ;) -nathan On 7/13/07, Robert Cummings <robert@xxxxxxxxxxxxx> wrote:
