configure HTTP1.1 pipline depth on Tomcat 5.0

[Feng Xie \(fxie\)]

Hi,
 
Is there any way to configure  HTTP1.1's persistent connection's
pipeline length  on Tomcat 5.0  ?  By pipeline length, I mean the number
of HTTP request could be sent by the HTTP/1.1 client before it gets back
the first response.
 
Thanks in advance,
Feng
