could two tomcat servers have mutual authentication?

[quanxin zhu]

 I setup a tomcat server 1 using client authentication, and deployed a
webservice on it.
So, when invoke the webservice, a certification is needed.
In server 2 , I want a servlet to invoke the webservice in server 1.
could server 2 automatically provide its certification to tomcat 1 when
invoke webservice?
