Http-access2 question

I’m learning Ruby and trying to write small script to fetch data from
different web pages using http-access2. Playing with my own apache web
server with mod_bw installed ( I
have faced the problem when I don’t receive the whole page, but only
8192 bytes.
Without mod_bw everything works fine.
Googling gave me, this message: with
very similar problem, but suggestion to use net/http instead of
http-access2 looks like not good idea for me.

Any help, guys?
