What is the advantage of using CGI.pm to print the header?

    For one thing is less typing :) Also more recent versions of CGI.pm will print a header like :

    Content-Type: text/html; charset=ISO-8859-1
    which is recommended in a CERT Advisory ... this is one of the advantages of using a module, they often get quietly updated like this long before the information that gave rise to the update has been as widely propagated.

    /J\

      Technically, CGI.pm also is cross-platform, that is, it uses the correct CRLF (newline) sequence that is needed for the browser to parse them, on all platforms. As many have pointed out, this is usually a non-issue, as most (modern) web servers correct such things on the fly, before sending the response, but it doesn't hurt in case someone, for some reason, would run your program under one that doesn't. :)
