[OpenLayers-Users] strategy refresh ol2, how stop it?

[emeotero]

Hi,(sorry for my English)I've a GeoJson vecLayer and I use a PHP postgress
query , the result goes to a Geoext Store that i reload after the query and
show the results on the map perfectly. I decided to show those results in a
cluster, it's makes me halfway, until you don't reload the page it doesn't
load well. I got a strategy to refresh the vecLayer, but only works if i put
a refresth interval. I want to stop this interval and it waits for the next
run. For more than i look for this i don`t find an example of how to do it.
Does anyone know how to do it? ...var interval = 1000;...vecLayer2 = new
OpenLayers.Layer.Vector("vecLayer2", {			  projection:
map.displayProjection,		 	/*preFeatureInsert: function(feature) {			
feature.geometry.transform(fromProjection,toProjection);			   },*/			  
protocol: new OpenLayers.Protocol.HTTP({				
url:'data/xxx'+sessionid+'.json',					format: new
OpenLayers.Format.GeoJSON(),				}),			   strategies: [					new
OpenLayers.Strategy.Fixed(),					new OpenLayers.Strategy.Cluster({distance:
20}),					new OpenLayers.Strategy.Refresh({active:true, interval:interval}),			
],			   styleMap:new OpenLayers.StyleMap({					"default": style,				
"select":{						fillColor:"#e3f0ff",						strokeColor:"#1eas1a"					}								
}),				displayInLayerSwitcher: false,				renderers:["Canvas", "SVG", "VML"],		
})...store = new GeoExt.data.FeatureStore({		autoDestroy: true,	
layer:vecLayer2,		root:'features',		fields:[			{name: 'id', type: 'double'},		
{name: 'name_es', type: 'string'},			{name: 'description', type: 'string'},	
],		proxy: new GeoExt.data.ProtocolProxy({				protocol: new
OpenLayers.Protocol.HTTP({						url: "data/xxx"+sessionid+".json",					
format: new OpenLayers.Format.GeoJSON()				})		}),	});use Ajax to execute
the query and load the store.I want to stop the strategy refresh until the
next query.
