hey fellas,

I recently wrote a flash uploader that is integrated into my rails  
app. What I want to do is feed the flash a var, have it do its thing,  
then feed a var back to the ruby.

My only issue is passing back the variable to rails. Does a post  
function like in PHP work? or does anyone have a simple solution for  
me?

Thanks, any advice you can throw my way i would greatly appreciate it.

Austen

Ogle the source to Juggernaut. It uses the URL javascript:source trick  
to  
push JS out into a browser.
