[OpenLayers-Users] Real-time image in Openlayer

[Greg Allensworth]

It's true, that WMS.redraw() doesn't seem to really force it. Try this 
trick:

    refresh_test.mergeNewParams({ blah:Math.random() });
    refresh_test.redraw(true);

This changes the URL string to include a blah= &param which will be 
different every time, thus tricking your browser cache.

Arnie's method of using time can work too; either should be just fine.
