Yo,  
I’ve got this data POSTing from a Flash App and I need to figure out  
how this little \<%= token\_tag %\> works so I can give the Flash the  
proper validation. See, I get this  
ActionController::InvalidAuthenticityToken because you know, gotta  
defend those POSTs, but how do I get the toke into my Flash?

I’m somewhat new, so if there is some way obvious easier way then let me  
know.

I’ve just been adding

:form\_authenticity\_token =\> form\_authenticity\_token

to my url\_for params.
