Deprecated. See wms-long-url.html for the recommended way to avoid long URLs.
This example uses a large SLD created on the client side to style a WMS
layer. This example uses a WMS.Post layer which transfers data via the
HTTP-POST protocol.
NOTE: Opera is not able to display transparent tiles with this layer,
and in some Firefox browsers can appear ugly viewport-shaking effects
while dragging arround. Use the 'unsupportedBrowsers' property to
control which browsers should use plain image tiles (like Layer.WMS)
instead. The default setting (["mozilla", "firefox", "opera"])
excludes problematic browsers without removing the ability to use long
request parameters, because all these browsers support long urls via
GET.
