How can I extract non-standard HTTP headers using Perl's LWP? <p>I'm working with a web application that sends some non-standard HTTP headers in its response to a login request. The header in question is:</p> <pre><code>SSO_STATUS: LoginFailed </code></pre> <p>I tried to extract it with LWP::Response as <code>$response-&gt;header('SSO_STATUS')</code> but it does not work. It does work for standard headers such as <code>Set-Cookie</code>, <code>Expires</code> etc.</p> <p>Is there a way to work with the raw headers?</p>
