title: nginx and tomcat (with memcached session manager) config context cookies="false"
body: <p>I had some tomcat7 with memcached session manager, use nginx to proxy tomcats, it's ok.</p>
  
  <p>But now, we need to pay on iphone safari, and access by a url with jsessionid.
  So add cookies="false" to tomcat context.
  Then we will lose session very access(with jsessionid in url).
  But, when use nginx and one tomcat server, or directly access tomcat server, every thing is fine.</p>
  
  <p>Why is happend?
  Did anyone can solved this problem.
  Thanks</p>
