Roo.data.DataProxy
Roo.data.HttpProxy

Class Roo.data.HttpProxy

Package:	Roo.data
Defined In:	Roo/data/HttpProxy.js.
Class:	HttpProxy
Extends:	Roo.data.DataProxy

An implementation of {link Roo.data.DataProxy} that reads a data object from an {link Roo.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 {link Roo.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".

Public Methods
Method		Defined By
	new Roo.data.HttpProxy (Object *conn) Create a new Roo.data.HttpProxy Create a new Roo.data.HttpProxy Parameters: Object conn* Connection config options to add to each request (e.g. {url: 'foo.php'} or an {link Roo.data.Connection} object. If a Connection config is passed, the singleton {link Roo.Ajax} object will be used to make the request.
	getConnection () : Connection Return the {link Roo.data.Connection} object being used by this Proxy. Return the {link Roo.data.Connection} object being used by this Proxy. Returns: Connection The Connection object. This object may be used to subscribe to events on a finer-grained basis than the DataProxy events.	Roo.data.HttpProxy
	load (Object *params, Roo.data.DataReader reader, Function callback, Object scope, Object arg) Load data from the configured {link* Roo.data.Connection}, read the data object into a block of Roo.data.Records using the passed {link Roo.data.DataReader} implementation, and process that block using the passed callback. Load data from the configured {link Roo.data.Connection}, read the data object into a block of Roo.data.Records using the passed {link Roo.data.DataReader} implementation, and process that block using the passed callback. Parameters: Object params An object containing properties which are to be used as HTTP parameters for the request to the remote server. Roo.data.DataReader reader The Reader object which converts the data object into a block of Roo.data.Records. Function callback The function into which to pass the block of Roo.data.Records. The function must be passed The Record block object The "arg" argument from the load function A boolean success indicator Object scope The scope in which to call the callback Object arg An optional argument which is passed to the callback as its second parameter.
