Remember, HTTP is a stateless protocol. Without adding any extra magic, if a user visits your site twice in a row, as far as the web server is concerned, those are two totally separate visits having nothing in common with eachother (save for coming from the same IP address).

If you want your web server to be able to remember users between pages they visit, you need some way to create a "session" -- some way to save information about the user so you can recognize them the next time they request a page.

The most common way to do this is by using cookies.

So, sessions are what you want, and cookies are most often how you get them.

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 or How to display code and escape characters are good places to start.
