Better to declare them in httpd.conf or a startup.pl type script.
# httpd.conf PerlModule Date::Manip # or startup.pl use Date::Manip ();

This allows them to be cached on server boot and shared between child processes. The () after the module in startup.pl is very important as it means the module won't polute your global namespace (exports nothing).

This gives you the performance advantage of having the module already compiled and cached, while keeping your memory requirements (per child) down. Make sure to still use the module in your hanlder/script though; while not always nesseccary it gets pretty confusing if you don't.

If you're running Apache::Registry or PerlRun the rules are slightly different. Check the guide for more info.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • 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.
