See merlyn's Watching long processes through CGI, which demonstrates a technique to display a "please wait" screen until a program has finished running.

    I was completely blind, maybe because I didn't understand what merlyn did there. Now I C. If I have understood it correctly, your program output is saved in $cache and once it is filled the CGI prints your results, otherwise (if $cache is empty) it prints "Wait please", right?
