dynamic layer filter, again

[Stephen Davies]

Yes, provided you include the map_ prefix.

That is, use:

...&map_layer1_filter=expr1&map_layer2_filter=expr2....

I am currently changing three filters with each URL and it works just fine -
as does just about everything else in Mapserver; I reckon it's great.

Cheers,
Stephen
