WrkTaskIP.aspx Task Page Change Redirect URL

I have a workflow with customised task forms so clicking on a workflow task opens up the task page WrkTaskIP.aspx with an InfoPath form hosted within it.

The task form has a submit button which submits to the hosting environment to c开发者_Go百科omplete the task and the page by default will then redirect to the WrkStat.aspx page to display the status of the workflow after submitting the task.

However I would like to be able to change this default redirection to another URL which I would normally do by modifying the &Source parameter in the URL however this time I have no control over this.

Is there any way to achieve the redirection to another URL in this situation?

(That does not involve a global change to a _layout form)

Any help would be much appreciated.

I got around this problem by having a task form change view to a "Task Completed" screen on submit which then includes a link to the place they should be redirected to.

Since I already have found a way to get hyperlinks to open in the same window, it nearly has the same effect as what I was originally after.

The customers were actually happy with this because it confirmed to the user that they had completed the task rather than just redirecting after clicking submit.
