<h1><a name="description">DESCRIPTION</a></h1>
<p><em>HTTP::Status</em> is a library of routines for defining and
classifying HTTP status codes for libwww-perl.  Status codes are
used to encode the overall outcome of a HTTP response message.  Codes
correspond to those defined in RFC 2616 and RFC 2518.</p>

<h1><a name="functions">FUNCTIONS</a></h1>
<p>The following additional functions are provided.  Most of them are
exported by default.</p>
<dl>
<dt><strong><a name="item_status_message">status_message( $code )</a></strong>

<dd>
<p>The <a href="#item_status_message"><code>status_message()</code></a> function will translate status codes to human
readable strings. The string is the same as found in the constant
names above.  If the $code is unknown, then <a href="../../lib/Pod/perlfunc.html#item_undef"><code>undef</code></a> is returned.</p>
</dd>
</li>
<dt><strong><a name="item_is_info">is_info( $code )</a></strong>

<dd>
<p>Return TRUE if <code>$code</code> is an <em>Informational</em> status code.  This
class of status code indicates a provisional response which can't have
any content.</p>
</dd>
</li>
<dt><strong><a name="item_is_success">is_success( $code )</a></strong>

<dd>
<p>Return TRUE if <code>$code</code> is a <em>Successful</em> status code.</p>
</dd>
</li>
<dt><strong><a name="item_is_redirect">is_redirect( $code )</a></strong>

<dd>
<p>Return TRUE if <code>$code</code> is a <em>Redirection</em> status code. This class of
status code indicates that further action needs to be taken by the
user agent in order to fulfill the request.</p>
</dd>
</li>
<dt><strong><a name="item_is_error">is_error( $code )</a></strong>

<dd>
<p>Return TRUE if <code>$code</code> is an <em>Error</em> status code.  The function
return TRUE for both client error or a server error status codes.</p>
</dd>
</li>
<dt><strong><a name="item_is_client_error">is_client_error( $code )</a></strong>

<dd>
<p>Return TRUE if <code>$code</code> is an <em>Client Error</em> status code. This class
of status code is intended for cases in which the client seems to have
erred.</p>
</dd>
<dd>
<p>This function is <strong>not</strong> exported by default.</p>
</dd>
</li>
<dt><strong><a name="item_is_server_error">is_server_error( $code )</a></strong>

<dd>
<p>Return TRUE if <code>$code</code> is an <em>Server Error</em> status code. This class
of status codes is intended for cases in which the server is aware
that it has erred or is incapable of performing the request.</p>
</dd>
<dd>
<p>This function is <strong>not</strong> exported by default.</p>
</dd>

<p>Wished @EXPORT_OK had been used instead of @EXPORT in the beginning.
Now too much is exported by default.</p>
