Configuring a JavaScript Remoting Request

Configure a remoting request by providing an object with configuration settings when you declare the remoting request.
For example, the default configuration parameters look like this:
{ buffer: true, escape: true, timeout: 30000 }
These configuration parameters aren’t ordered, and you can omit parameters you don’t want to change from the default.
JavaScript remoting supports the following configuration parameters:
Name Data Type Description
buffer Boolean Whether to group requests executed close to each other in time into a single request. The default is true.

JavaScript remoting optimizes requests that are executed close to each other in time and groups the calls into a single request. This buffering improve the efficiency of the overall request-and-response cycle, but sometimes it’s useful to ensure all requests execute independently.

escape Boolean Whether to escape the Apex method’s response. The default is true.
timeout Integer The timeout for the request, in milliseconds. The default is 30000 (30 seconds). The maximum is 120000 (120 seconds, or 2 minutes).
The request timeout can also be configured for all requests made by a page, by setting the timeout using the Visualforce remoting object:
<script type="text/javascript">

    Visualforce.remoting.timeout = 120000; // Set timeout at page level

    function getRemoteAccount() {
        var accountName = document.getElementById('acctSearch').value;

        // This remoting call will use the page's timeout value
        Visualforce.remoting.Manager.invokeAction(
            '{!$RemoteAction.AccountRemoter.getAccount}',
            accountName, 
            handleResult
        );
    }

    function handleResult(result, event) { ... }
</script>

Override a page-level timeout configuration on a per-request basis by setting the timeout in the configuration object for that request, as described above.
