[OpenLayers-Users] GeoRSS question

[Deli Soetiawan]

thanks for your help, i've notice that was a reloading function using
SetInterval
[i]setInterval(reload, 5000);[/i], and i think this function built-in on
OpenLayers so it will not make a problem

for browser cache thing, i could use php with transsid enable and regenerate
session every data reload, or like you have said before we could use
random_seed in our browser using JS (nicely done) :D

and thanks for confirming vector draw (line, polygon), now i should use GML
layer with GeoRSS format :D
