It's a good practice to redirect user to get requests after making some changes with post and this is
usually done by Spring WebFlow by default. But what if by some reason you need to use <webflow:always-redirect-on-pause value="false"/> option?
You can do this through java code. This approach is not described in WebFlow reference but documented via API javadoc.
Suppose you have some Action which is configured through WebFlow. If you want to make redirect to GET after this action you can modify action methods in following way:

public Event saveMyItem(RequestContext context) {
//do some operations here

//issue redirect
return success();

When WebFlow starts generating HTTP response it will send 302 code.
