[OpenLayers-Users] MapServer to OpenLayers line rendition

[Steve Lime]

Looking back at the original email Aileen sent there was a reference to this layer creation code:

  var myqry = new OpenLayers.Layer.MapServer.Untiled("Map", "/cgi-bin/mapserv?", {map: '/home/to/my/map.map', layer:'#qrylayer#', map_#qrylayer#:'classitem+#qryitem#+expression+#q.code#', format: 'gif', transparent:'false'});

The interesting part to me is:

   map_#qrylayer#:'classitem+#qryitem#+expression+#q.code#'

That syntax has undergone change from 4.10 to 5.0. It looks like you're changing an expression on
the fly which isn't allowed any more, but there are work arounds. As Chris says what I'd like to see
are the URLs actually being passed to MapServer. You should be able to intercept and share those.
