function hook_authcache_cookie_alter in Authenticated User Page Caching (Authcache) 7.2

Modify information about cookies set by other modules.

In this example the simple nocache-cookie is replaced with a a HMAC bound to the session. Note that for this example to be effective it is necessary to implement a corresponding validation function suitable for the caching backend in place. Point the variable authcache_builtin_nocache_get to the name of an appropriate implementation when the default builtin cache backend is used.

$conf['authcache_builtin_nocache_get'] = 'my_nocache_get';
