Hi. For a CGI script I am creating on Apache/Win32, I need to emulate CGI "server push" to show real time status of CGI script by logging progress to the client. As the CGI script runs, I need to show to the user what the script is doing. I need to support all browsers: IE, Netscape, and Opera.

I would like to be able to update the contents of a textarea dynamically. Is is possible using hidden frames and Javascript? What is Javascript stream-emulation?

IE does not support CGI server push and so I need to use a technique that will work for all browsers.

Are there CGI widgets I could use for this purpose? Any modules or tools I am overlooking?

The real problem is that I am using WWW::Mechanize to automate other web sites from the script. I do not want the client to time-out waiting for the CGI script to complete. How do I keep-alive the Client connection to never let the user see a time-out? I also do not want to slow down the scripts by creating a lot of traffic. I am currently using using POE::Component::Client::HTTP to simultaneously check the response times of all the web sites I will automate. My manager does not want the user to think the script has hung or is not responding.

I am also looking into using LWP::Parallel::UserAgent. Is LWP or WWW::Mechanize thread-safe for using 5.8.0 threads? Is threading on CGI worth the effort?

Any help is appreciated. Thanks.
