// Note that cometd _base is _not_ required, this can run standalone, but ifyou want
// cometd functionality, you must explicitly load/require it elsewhere, and cometd._base
// MUST be loaded prior to HttpChannels ifyou use it.

// summary:
//              HttpChannels - An HTTP Based approach to Comet transport with full HTTP messaging
//              semantics including REST. HttpChannels is exactly the same as RestChannels, loading HttpChannels simply ensures that http parsing
//              capabilities are present for application/http messages

// description:
//              This can be used:
//              1. As a cometd transport
//              2. As an enhancement for the REST RPC service, to enable "live" data (real-time updates directly alter the data in indexes)
//              2a. With the JsonRestStore (which is driven by the REST RPC service), so this dojo.data has real-time data. Updates can be heard through the dojo.data notification API.
//              3. As a standalone transport. To use it as a standalone transport looks like this:
//      |               dojox.cometd.HttpChannels.open();
//      |               dojox.cometd.HttpChannels.get("/myResource",{callback:function(){
//      |                       // this is called when the resource is first retrieved and any time the
//      |                       // resource is changed in the future. This provides a means for retrieving a
//      |                       // resource and subscribing to it in a single request
//      |               });
//      |       dojox.cometd.HttpChannels.subscribe("/anotherResource",{callback:function(){
//      |               // this is called when the resource is changed in the future
//      |       });
//              Channels HTTP can be configured to a different delays:
//      |       dojox.cometd.HttpChannels.autoReconnectTime = 60000; // reconnect after one minute
//
dojox.cometd.HttpChannels = dojox.cometd.RestChannels;
