Flowscript continuation from external reply

Hi,
I have a flowscript function which passes some variables to an  
external site. The site will send back a success or failure  
confirmation based upon the parameters passed. What I want to do next  
is continue on the from the next point in time after the external  
site was contacted, so:

I want to create some flowscript which passes variables to an  
external site, (https://www.externalsite.com/test.asp?contiuation- 
id=xxx, var1=x,var2=x) for example, gets a response back from the  
external site (http://www.mysite.com/continuation-id/value-returned),  
and based on the response sent back does something else following the  
initial call to the external site. How do I do this in flowscript?

So what i'm thinking is something like:

function getResults() {

	cocoon.redirectTo("https://www.externalsite.com/test.asp?contiuation- 
id=xxx, var1=x,var2=x")

	if (value-returned == 'true') {
		do this
	}else{
		do this
	}
}

How do I get back to the point after cocoon.redirectTo() using the  
returned continuation-id?

thanks in advance

Andrew

This is not simple. If you can manipulate the return url, try to have 
the value-returned passed as a parameter (like 
www.yoursite.com/continuation-id.continue?value-returned=X ) .

If you can't, then you will have to parse the URL by yourself inside the 
flow, and to do this you have to access the underlying JAVA request 
object, since the FOM object does not have methods to access the requestURI.

This is dirty, and YMMV, but it's done this way :

var objectmodel = 
Packages.org.apache.cocoon.components.CocoonComponentManager.getCurrentEnvironment().getObjectModel();
var jrequest = 
Packages.org.apache.cocoon.environment.ObjectModelHelper.getRequest(objectmodel);
var uri = jrequest.getRequestURI();
var value-returned = uri.substring(uri.lastIndexOf('/') + 1);

I don't know of a way to pass parameters from the sitemap to a 
continuation (you can pass them with <map:parameter inside a <map:call 
function, but i don't think they will work inside a <map:call 
continuation ).

OR you can try to rewrite the url, (a match that uses a map:redirect-to 
uri="{1}.continue?value-returned={2}") but it's getting dirtier and 
dirtier and don't know if it works well at all.

<map:match pattern="CCreturn/*/*">
   <map:redirect-to uri="{1}.continue?value-returned={2}"/>
</map:match>

Hope this helps,
Simone
