[jetty-users] HttpGenerator: Ignore extra content

[Srinivasa Yellapu <srinivasaven@xxxxxxxxx>]

Hi,
i am developing a webapplication which uses dwr for push mechanism. i
observe the PrintWriter object in HttpServletResponse is getting set with an
error.
Logic:
*dwr's custom flush method:*
PrintWriter out = reponse.getWriter();
public boolean flush() {
  out.flush();
 if (out.checkError()) {
   /* Error occurred while sending the response, so resend the response in
the next push */
   return false;
 }
 /* response sent successfully */
 return true; 
}

*The strange thing is that even though PrintWriter with error successfully
sends response to client side, since in the above code out.checkError() will
return true, response will be resent to client.*

On further observation i found that the following statement getting logged
everytime when this kind of misbehavior is there:
   WARN:oejh.HttpGenerator:Ignoring extra content

 This is dependent on browser type and this is happening in chrome, firefox
and not in opera, IE.

1. Is this (HttpGenerator: Ignoring extra content) going update anything to
PrintWriter ?
2. When PrintWriter sets error flag ?
3. How browsers response to this kind of response (HttpGenerator: Ignoring
extra content) ?

Please someone guide me to solve this issue.

Thanks & Regards,
Srinivasa Yellapu
