In addition to passing hidden form elements between pages and potentially employing some of merlyn's above mentioned techniques, you might consider session management through the use of Apache::Session.

Granted this is a server-based session-management solution and requires the installation of Apache webserver and mod_perl (optionally MySQL or PostgreSQL), so YMMV.

Just throw in a Web application development framework like HTML::Mason or Text::Template and you too could be the next amazon.com!!!! :) see princepawn's node for some framework starting points...

<tip>When using server-based session management, instead of storing lots of user data in the session consider storing only the row id from the user's login profile in the session. That way with one quick query to the database on a page reload you have all the user profile information. There are of course pros and cons to this, but for some applications such a technique would be desirable. </tip>

• 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.
