[OpenLayers-Users] WMS Layer not supporting SRS parameters

[ITBeyond]

Thanks Chris,

So if I am adding google maps and other maps using different projections and
then adding multiple WMS layers which may be in different projections how
does this work? My issue seems to only occur when I use isBaseLayer = false
(hence trying to output the WMS layer on top of a google or custom map). As
the OL code seems to ignore the projection parameter when isBaselayer =
false it defaults it to 4326 (which is not listed anyway in my code. If I
check the isBaselayer = true the URL has my projection in it. So in a nut
shell changing the isBaseLayer value seems to use or ignore the projection
parameter in my WMS layer is this correct?
