title: Premature end of script headers on one server but not another
body: <p>I have two servers.  They are both running the same code and are connected to the same database.  But when I make a certain ajax call, one server works fine, and the other throws an Internal Server Error. Inside the Apache log of the internal service error server, it says 'Premature end of script headers'. This makes me think that there is some Apache error on one machine, but the Apache folder looks identical on both machines.</p>
  
  <p>What sort of differences between servers would cause one to throw this error?</p>
