Cache Ajax requests so you don’t do the same thing twice.
Syntax is the same as Ajax.Request, but if it has already performed that request you’ll get the data right back.
At the moment it doesn’t try and guess based on url/params and you have to name the cache, but in future versions this won’t be necessary.
If a request is in progress, you’ll get the results when they come in.
new Ajax.CachedRequest("/data", {
method: "post",
name: "some_name",
onComplete: function(transport)
{
// do something...
}
});
