As far as I know, there is no turbine module included in turbine to handle
your flow as there is in struts.
You can however send http redirects back to the user. These will tell the
browser that the page has moved and it should use the new page (of course
the server has already processed the post request/action).
Here is some sample code of how to do a redirect to be executed after you
handle the request and want to redirect the client.
public void redirect(RunData data, String page) throws Exception {
TemplateLink tl = new TemplateLink(data);
tl.setPage(page);
// tells the browser where to get the new page
data.setRedirectURI(tl.getURI());
// tells the browser page has moved
data.setStatusCode(302);
}
