This is the legacy cookie parser based on RFC6265, RFC2109 and RFC2616. relax the behaviour of this cookie processor if required. Use of self-signed certificates creates a lack of integrity and invalidates the certificate based authentication trust model. Class 3 PKI certificates are used for servers and software signing rather than for identifying individuals. The Tomcat manager application is used to manage the Tomcat server and the applications that run on Tomcat. This setting affects. org.apache.tomcat.util.http. If this is true Tomcat will treat the forward slash to ignore the Max-Age parameter in a SetCookie header.
