title: ajax request browser limit
body: <p>A more generic questions to start. Is there a limit to the response size of an ajax request, if it is a JSON request?</p>
  
  <p>I am passing large amounts of data through a JSON request and running into a 'script stack quota is exhausted' message in FF3. Now in FF2 the quota was 4mb but in FF3 it is 640kb. I am wondering if this is JSON specific somehow. Do normal ajax requests have a response size limit? One that may be imposed by the browser? If a non-JSON request doesn't have these same issues with script stack quota, how could I categorize the data coming back? XML perhaps...Im not sure if I would be within the bounds of the w3c spec with my data to do so.</p>
