A data proxy for use with OpenLayers.Protocol.WFS objects.
This is mainly to extend Ext 3.0 functionality to the GeoExt.data.ProtocolProxy. This could be simplified by having the ProtocolProxy support writers (implement doRequest).
Configuration properties in addition to those listed for Ext.data.DataProxy.
Number Optional limit for number of features requested in a read. No limit set by default.
Boolean If set to true, geometries will be casted to Multi geometries before writing. No casting will be done for reading.
String WFS version. Default is “1.1.0”.
