How can I do that when I chain actions?. I mean, the second action is chained
after the first one, but there are situations in which there is no chaining at
all(both actions can be executed indepently) or the chaining can be the other
way. In all cases I need to keep only the last cookie generated. I can keep a
set of cookies in the request, but how I can put them into the request after
all the processing has been done? Since if I chain the actions, there is no way
to know programatically which is the last one, right? Or is there?
Thanks
Jose

Save cookies outside the request then, and only add the cookie at the last
minute.
