Thanks for your suggestion of using $form['#redirect'].  That's working for 

I was having trouble choosing from all the options for sending the user 
elsewhere after submitting a form.  As I understand it, the options are...

1) set $form['#action'].  Useful if you are posting the data elsewhere.  In my 
case this would have prevented validate and submit callbacks from being 
2) set $form['#redirect'].  Useful if you know in advance where to send the 
user after submit callbacks.
3) have your submit callback return the URL to redirect to.  Useful to 
dynamically determine where to go next.  If multiple submit callbacks, only 
one will be honored.  Loses to $form['#redirect'] if both are specified.
4) set ?destination= in the URL, or $form['destination'] as a form element.  
Unlike the other methods this works only with local paths.  Takes priority 
over options 2 and 3.  This is not part of the form api, it's part of

I wanted to ask here in case this was done on purpose.  I.e. to prevent a 
cross site scripting attack or some such.

I don't want to post to an external site.  I want to redirect there after 
submit handlers have been called.
