| Class: | HttpProxy |

| 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".
