texte = Sorry for the delayed response, Christmas holidays and all. Happy NewYear everyone!Dylan, after reading your response I think I need to explain in moredetail. I need the software to check on the status of a database and aplain text file every few seconds. When the software detects that thedatabase or the file has changed, it must send a response to allconnected visitors.I'll be keeping connections open to these visitors for the solepurpose of sending them an update every few seconds. An update will besent whether or not something has changed since the last update. Thisis necessary to keep visitors informed that they are still online andconnected.I've read that triggers are buggy so I don't think I should rely onthem until they are fixed. This checking and updating capability isabsolutely critical to the application, so this may mean it should bedone with cron. If this software can interface with cron and run cronevents can someone post a code example to help me get started?I run Linux servers exclusively, and I could have hundreds of serversrunning this distributed online system at any given moment. They aregeneric servers, not all the same OS and not all the same hosts, soI'll need software that works on all of them. From what I've read itlooks like the company is building such a new version for Linux somaybe this is good timing.-----------JasonOn 12/21/08, Dylan Wood
