# Basic WMS Example via HTTP-POST protocol with a large SLD included

Creating a WMS layer with a large SLD in the sld_body
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.
