Associating a task to an external URL

[eslxst]

I am trying to figure out if it is possible to use Activiti or Alfresco Process Servicesin a particular way where:

• One or more task of the process opens a form in our Web Application by invoking a URL and passing some input parameters.
• The process engine understands if the step has been completed based on output parameters or on the call to a Web Service to know the state of the process instance.

So to summarise, is it possible to associate a task to an external URL to open a form produced by our web application?

Could you please help where to start? or provide some resources?

Many Thanks

Yes it can be done, but that's part of your application logic. 

You will need to map a task id to your external link which you will need to generate. 

Does that make sense?
