Class Ext.data.HttpProxy

Package:	Ext.data
Class:	HttpProxy
Extends:	Object
Defined In:	HttpProxy.js

An implementation of Ext.data.DataProxy that reads a data object from an Ext.data.Connection object configured to reference a certain URL.

Note that this class cannot be used to retrieve data from a domain other than the domain from which the running page was served.

For cross-domain access to remote data, use an Ext.data.ScriptTagProxy.

Be aware that to enable the browser to parse an XML document, the server must set the Content-Type header in the HTTP response to "text/xml".
