If you are writing a CGI program, you need to make sure your program returns the proper HTML to the server before exiting. You shouldn't just exit the program prematurely. You need to anticipate all of the errors that might occur and handle them correctly, generating the proper response to the user. Are you using the CGI::Carp module? This module will generate error pages, but you should only depend upon these pages during development. Your users will not care that your program has encountered an unhandled bug. See <http://perldoc.perl.org/CGI/Carp.html> for what the module will do for you. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
