在谷歌应用程序引擎java上的HttpOnly cookie

Question

Anyone know how I can use httponly cookies for sessions and cookies on the app engine?

In the javadoc for the Cookie class, http://java.sun.com/javaee/6/docs/api/javax/servlet/http/Cookie.html#setHttpOnly(boolean) , there is a setHttpOnly method.

I get a compiler error when trying to use it when developing for app engine though.

The method was introduced in the Servlet 3.0 spec, so its pretty new.

Answer 1

App Engine supports the Servlet API at version 2.5, so you cannot use the setHttpOnly method.

You could try to output the cookie header yourself.

resp.setHeader("Set-Cookie", "A=7; expires=Fri, 31-Dec-2010 23:59:59 GMT; path=/; domain=.example.net; HttpOnly");

Answer 2

Since 2017 GAE does support servlet API 3.1 So I've tested the following cookie option inside web.xml and it works:

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