How about this deviation on the same theme:

use CGI ':standard';

print CGI->redirect(-location=>"http://www.food.com/bar.html");

Better yet, why not do some configuring in Apache. You could redirect the user to a diffent web page depending on the error message. Here are examples for error 404 and error 500, which are typical ones, that you could add to /etc/httpd/conf/httpd.conf configuration file or even to a .htaccess file.

ErrorDocument 404 /error_msgs/error_notfound.html
ErrorDocument 500 /error_msgs/error_scriptproblem.html

See this article on Apache Redirection from Unix Review.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
