What I want is the data coming back be small as possible.

According to FireBug's XHR inspector ("Net" tool), this is the HTTP
response header for my request:

Server:	Swazoo 2.0 Smalltalk Web Server
Cache-Control: no-cache
Content-Type: text/html;charset=iso-8859-1
Date: Mon, 07 Jan 2008 13:27:55 GMT
Content-Length: 0

But in that response, the size reported by FireBug is 4kb, even when
the HTTP header says zero, and the "Response" tab in that request,
shows a lot of content (that 4kb).

I'm not obsessed with the HTTP headers, but I am looking how to reduce
the HTML content.

Thank you.
