I'm talking about different hosts. Sorry for not being clearer. What I meant is that a URL does not necessarily specify which host a http daemon is active on. For instance, you could have 20 boxes that all correspond to one URL--http://foobar.com for example--that alternately serve pages to balance the load. I'm sure you already know all this.
So, now the question is, what is the best way to test how each individual host's http daemon is doing? The only way I know how is by telnetting into that host's port 80 and doing a HTTP get. IO::Socket::INET sounds interesting, although I don't quite understand how it differs and I haven't successfully implemented it yet.

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).
