Is there a 'http response sampler' in Jmeter

Hi,
 
I am planning to do  a  performance and load testing on our server.
A simplified configuration and flow is listed below:
 
              1.  http
2.  http/soap
Client -----------------> Web Server under test
------------------------>  Third party Authentication Server
         <------------------
<------------------------
              4.  200ok
3.   200 ok
 
 
 Based on my understanding,  Jmeter  can be used  to replace the Client
and generate  http get/set traffic using the http request sampler.
In order to simulate an end to end flow and performance I need a test
stub for the Third party Authentication Server to receive and response
to the SOAP request.
 
I wonder whether I can configure Jmeter to do that.  Is there a 'http
response sampler'?  In short can I configure jmeter to receive and
process http event rather than generate post/get  event?
 
Suggestions and comments are greatly appreciated.
 
Thanks
