What is the cleanest way to display a static HTML document in CGI, based on the current date?

i.e. User accesses main.cgi
and the script outputs to monday.html, tuesday.html etc... based on the current date..

use CGI qw(redirect);
use POSIX qw(strftime);

$day = lc(strftime("%A", localtime));
print redirect(-uri=>"$day.html");

The redirect URL can be a relative path as well, if you'd like.

Can you check apache's logs to see what the error was?

Here's an alternate (not so clean) version:

     my @days=qw( sunday monday tuesday wednesday thursday friday saturday);
     my $day=$days[ (localtime)[6] ];
     print "Location:$day.html\n";

That last one, screwed up as well....
error 500 misconfiguration....

I am not sure what is going on, It's not the server, and I am setting the correct chmod permissions because other scripts are working fine.

Any ideas, on formatting or adding includes??

The second one doesn't need any includes, all its functions are standard, as long as you're not using a really old version of perl.

Are you including the #!/usr/bin/perl or similar at the top?  Is it the same path used in your other scripts?

What web server are you running?  Do you know if you're able to look at the server's error logs?  (they'll show you some problems with your script, not just with the server setup)

Try adding the following lines to the begining of your script, and if the error is only in the perl script, it'll display the errors to your browser instead of to the server log:
       ## death handler, presumes no output yet
       $SIG{``__DIE__''} = $SIG{``__WARN__''} = sub {
            my $error = shift;
            chomp $error;
            $error =~ s/[<&>]/``&#''.ord($&).``;''/ge;
            print ``Content-type: text/html\n\n[$error]\n'';
            exit 0;

My other perl scripts (working) have: #!/usr/bin/perl
as the first line....

same error even with Interiot's debugging death handler:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
