When you request a directory on a webserver the server gets to decide what to send you - usually index.html but not necesarily. This is straight ought of lwpcook.pod:
"If you just want to check if a document is present (i.e. the URL is
valid) try to run code that looks like this:
use LWP::Simple;
if (head($url)) {
# ok document exists
}
. . ."
. . . which is the "canonical" way to make sure a url is valid.
Cheers,
Erik

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).
