Hi Nalin and Hans-Bernhard,

The short answer, as Hans has stated is: NO.
The slightly longer answer is: why would you want to do this? there maybe a
better way to complete your goal - serverside gnuplot image generation?

The longer answer is: Maybe,

First, you could configure your webserver to send a customised mime type
when your stream is selected by your browser. You could then configure your
browser to delegate activity to another application (gnuplot) when it
encounters this type.

Secondly, there exist scrips which will allow the gnuplot to print from
STDIN. You may be able to connect STDIN to the web stream.

By achieving these two tasks, you may be able to get the behaviour you have
loosely specified.

cheers,
