[OpenLayers-Users] Refresh an indepent Layer... every n seconds...

Fri Aug 1 13:16:38 EDT 2008

Sorry, counter has to be in lowercase and I have thought the layer would be
a WMS layer. For Mapserver layers there seems not to exist a redraw
function. Perhaps this will work:

add counter to the params of your Mapserver layer and in your redraw
function use recorridos.params.counter++; 
This should change the url for your request, but i don't know, wether this
updates the layer.

Otherwise i have no idea.
