As in Caching Web Pages, you probably want to look in to using Squid Cache to do the dirty work for you. Barring that, maybe you could store a date field in the DB and check if you need to resend. You can send your own "304" header using CGI, after all.

By the way, you should probably be using placeholders, like this:
my ($file) = $dbh->selectrow_array("SELECT $image FROM offerte WHERE id=?", {}, $id);
It may not make a difference in your particular case, since you are using numeric data, but I'd argue it should be done out of principle. If you always use them, you don't have problems with mistyped data.

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.
