koolade's suggestion echoes an approach that has worked
well for me. Here's a bit of (slightly
verbose) code to illustrate:
sub make_rand_str {
my $num_chars = shift;
my @possible_chr_array = @_;
my $num_possibles = @possible_chr_array;
my $rnd_str = "";
for (my $i=$num_chars; $i--;) {
$rnd_str .= $possible_chr_array[rand($num_possibles)];
}
return $rnd_str;
}
my $rnd_str = make_rand_str(4, "A".."Z", "0".."9");
my $url = "http://my/host/cgi/script.pl/$rnd_str",

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).
