<p>Apache::*::Error - Exception classes for Apache::Request, Apache::Upload, Apache::Cookie::Jar and Apache::Cookie</p>

<pre>

<h1><a name="description">DESCRIPTION</a></h1>
<p>This manpage documents the Apache::*::Error classes provided by
the Apache::Request, Apache::Upload, and Apache::Cookie modules.
Error classes are all derived from APR::Error and the class
which first produced the error. Unlike the object that created it,
an Error object will not itself throw an error by calling its methods.</p>
<p>
</p>
<hr />
<h1><a name="apache__request__error">Apache::Request::Error</a></h1>
<p>These exceptions are derived from APR::Error and Apache::Request,
and indicate that an error occurred during param parsing.</p>
<p>
</p>
<hr />
<h1><a name="apache__upload__error">Apache::Upload::Error</a></h1>
<p>These exceptions are derived from APR::Error and Apache::Upload,
and indicate that some Apache::Upload method failed (often caused
by a filesystem error).</p>
<p>
</p>
<hr />
<h1><a name="apache__cookie__jar__error">Apache::Cookie::Jar::Error</a></h1>
<p>These exceptions are derived from APR::Error and Apache::Cookie::Jar,
and indicate that the cookie parser failed to successfully parse the
incoming Cookie header.</p>
<p>
</p>
<hr />
<h1><a name="apache__cookie__error">Apache::Cookie::Error</a></h1>
<p>These exceptions are derived from APR::Error and Apache::Cookie.
Their presence indicates that an Apache::Cookie method failed.
Typically they are caused by</p>
<pre>
1) attempting to bake(2) a non-compliant cookie,
2) attempting to set an unsupported cookie attribute.</pre>
<p>
