  Basic Hint
  `if you need a hint here is some example code: <../../class1/module1/irules/lab2irule_0.html>`__

  If you are really stuck, here is what we are looking for:

  #. `When HTTP_Request comes in <../../class1/module1/irules/lab2irule_1.html>`__
  #. `Log the headers from the HTTP_REQUEST <../../class1/module1/irules/lab2irule_2.html>`__
  #. `When HTTP_RESPONSE comes back <../../class1/module1/irules/lab2irule_3.html>`__
  #. `Log the response headers <../../class1/module1/irules/lab2irule_4.html>`__
  #. `Now remove the HTTP::header named Server <../../class1/module1/irules/lab2irule_5.html>`__
  #. `Now you should have enough to understand and the majority of code to create the iRule.  If not here is the complete iRule. <../../class1/module1/irules/lab2irule_99.html>`__
