You might try something similiar to webmin with nph scripts we use nph 
and local $| in house to do this.

also try using

local $| = 1

HANDLE->autoflush(EXPR)
$OUTPUT_AUTOFLUSH
       $|      If set to nonzero, forces a flush right away and after every
               write or print on the currently selected output channel.
               Default is 0 (regardless of whether the channel is really
               buffered by the system or not; $| tells you only whether 
you've
               asked Perl explicitly to flush after each write).  STDOUT 
will
               typically be line buffered if output is to the terminal and
               block buffered otherwise.  Setting this variable is 
useful pri-
               marily when you are outputting to a pipe or socket, such as
               when you are running a Perl program under rsh and want to see
               the output as it's happening.  This has no effect on input
               buffering.  See "getc" in perlfunc for that.  (Mnemonic: when
               you want your pipes to be piping hot.)
