Brendon,

I agree with you. Does it mean we can't do dynamic magic in CGI Perl?
If so, how can it happen? I had prior experience with JSP and
Javascript. JSP executes on server side and Javascript on the client.

What actually happens is when Javascript code is embedded inside a
server side script, client side code won't get interpreted by the
server. Server executes the server side part of it and evaluates it's
values and returns boh HTML and Javascript to the browser(client).

Client then displays HTML pages along with values returned by server.

I did this in JSP. But haven't ever seen how this can be done in perl.
So, I'd appreciate help.

Thanks again.
