Java应用程序Servlet 3中的httponly和安全标志

Question

I'm trying to setup an application with httponly and secure flags set to true but as soon as I edit my web.xml file by adding the requested cookie-config tag as follows:

 <cookie-config>
       <http-only>true</http-only>
       <secure>true</secure>
 </cookie-config>

I get a ViewExpiredException at the first command link submitted.

The complete session-config tag in my web.xml file is

<session-config>
    <session-timeout>5</session-timeout>
    <cookie-config>
        <secure>true</secure>
        <http-only>true</http-only>
    </cookie-config>
    <tracking-mode>COOKIE</tracking-mode>
</session-config>

I've been trying to understand what the error could be but can't find anything.

My managed bean is annotated as @SessionScoped while the command link is calling a method in the bean through ajax.

Answer 1

Secure on cookie means that the cookie will only be set for HTTPS connections.

If you access your app through http, the cookie will not be transmitted and there will be no session (and so no session- or view-scoped beans or the view state at all).

You can switch your state-saving to client-side, but what you actually want is using HTTPS.
