As long as you don't quit the handler you keep the connection open.

However I still have to investigate what are the issues with socket based 
protocol modules, there was a thread on the httpd-dev list saying that there 
some problems with it. So it's better to use bucket brigade based data 
manipulations.

it's not implemented in mod_perl, but in Apache 2 itself. You can look at the 
C source code and write similar in perl inside your handler. Most of the 
relevant logic resides in files starting with http_ in the apache source.
