// 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;
}
}};});
