If you're using mod_perl, your code is becoming part of the web server. Apache loads up your code during initialization. Your code isn't forked, executed, and killed. Instead, it's called when needed. After it returns, it remains resident to be called again when a new request for it arrives.

Since your code never runs down, your database connection remains open and the same connection will be used by the next request. This is one of the advantages to running under mod_perl - your module's initialization code gets executed once when Apache starts up instead of once per connection. As a result, you can get right down to processing the request which makes your application faster to respond.

90% of every Perl application is already written.

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.
