how to set chunk size?

[lior grinfeld <li...@gmail.com>]

Hi,

i am trying to find out where and which attribute i can use to do transfer
data as chunk and determined the chunk size of a response.
i saw it is supported, i read it in the "Apache Tomcat Configuration
Reference - The HTTP Connector", but where can i find more details?

thanks

Lior

Thanks Bill,

I already wrote a servlet that send chunked data, but since i saw in tomcat
document that tomcat support it, i thought it is something i can configure .
any way if my client support chunks i saw with wireshark that chunks size
are 2000 byte with default servlet , looks to me like default behavior of
tomcat. so probably you can set this value, so tomcat will do the job for me
( maybe better then me ??? :)  ) , so again - where to do it?


Regards
Lior

Section 5.1 of the Servlet spec might be a start :).  Setting the bufferSize 
on the response (assuming that this is a Servlet, not a JSP) should make it 
close to the chunk size (assuming you don't set it too small, like under 
8Kb).

There isn't really a practical way to guarantee the chunk size.  You would 
have to count bytes sent, and call response.flushBuffer at the magic number 
to have any chance of controlling the chunk size.

However, this should be a waste of time, since any working HTTP/1.1 client 
would know how to parse the chunk size sent in the response body.
