|
// 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

// 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
|
||
|
