title: Avoid flash upload 30 seconds timeout when doing imagemagic convert?
body: <p>I have a web app that uses a flash uploader (swfuploader) and recently a user pointed us to a bug that happens when the script hangs more than 30 seconds. </p>
  
  <p>I know flash documentation mentions that after 30 seconds of no response it will timeout, so i know i need to send some data to the browser before my convert function ends.</p>
  
  <p>As of now the script uploads the file, convert it, and if it is a multipage pdf it will save the reference children pngs to db, this works fine on big and small files, problem happens that after 30 pages it will hang for more than 30 seconds.</p>
  
  <p>Thanks in advance</p>
