title: Optional HTTP basic authentication in JMeter
body: <p>I have a request, which can be used on an endpoint with and without authentication too, but response is different in these cases. I send request to path like <code>/MyService?wsdl</code>. I tried to use <code>HTTP Authorization Manager</code> added it to <code>HTTP Request</code> element with whole url to this service, but it isn't working. I am sure, that username and password are correct. How is it possible to debug authentication process?</p>
