 This chapter is about Lenya/Cocoon's process for controlling Flow.

Flow is Lenya's method for passing control of the pipeline from the XMAP to a JavaScript function.
Specify where your JavaScript functions are by adding a Flow section, usually placed directly before the resources.
<map:flow language="javascript">
<map:script src="flow/myJavaScript.js"/>
</map:flow>
Transfer control in a pipeline:
<map:call function="doSomething">
<map:parameter name="requestURI" value="{request:requestURI}"/>
</map:call>
Parameters are optional.

MyJavascript.js
function doSomething(){
var requrl = cocoon.parameters["requestURI"]; // Get parameter sent from the XMAP
cocoon.sendPage("return-page"); // Return control to a pipeline in the current XMAP.
}
