This is not really the way perl works as such, but more along the lines of the stateless nature of HTTP.

There are numerous ways to maintain state that include:

  1. Tied hash
  2. A database
  3. regular old file
  4. hidden fields in the page...
In fact any method of retrieving the data can be used. The interesting part of maintaining state come along when you want to retrieve the data associated with a particular "session". You have to work out a method of branding the browser, then retrieving that branding and associating it with the data you've stored server side.

There are three main methods of branding a browser, cookies, in the URL and using hidden variables in your pages...

I wont go into detail, however, there is a wealth of information available all over the web, and here on perl monks.

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.
