One possible solution is to send the "please wait" page to the
user with a refresh directive in the HTTP header:
#!/usr/bin/perl -w
use strict;
use CGI qw/:standard/;
my $page= 'go_here_after_processing.htm';
print header(-refresh => "2; URL=$page");
print start_html, p('Please wait...'), end_html;
With (most?) browsers, this will display a plain page with the
"please wait" message, wait two seconds, and then load $page.
The problem with this approach is that you must specify the
number of seconds for the client to pause before loading the
target page, which may not be enough time for your processing to
complete.
I hope this helps.
