Hey Poul,
  Thanks for the prompt response and help.  However, I can't seem to get
this to work properly I am receiving the following error upon varnishd
startup:

Expected action, 'if' or '}'
In VCL code Line 7 Pos 16
                C{
----------------#-

Any help is appreciated as I believe that VCL is the best approach for
implementing this until something similar is implemented in varnish.  Thanks
again.
