Realizing vhosts with varnish

Hi Frank,

of couse you only need one single vcl_recv subroutine. This applies to 
all vcl subroutines.
I usually start with grabbing the default vcl and then add everything I 
need to the existing (default) subroutines.

If you use the include statement you have to keep in mind that inclusion 
is a textual
substitution - therefore no repeated definition of vcl_recv (or even 
other subroutines)
is allowed.

I did not try this myself using your vcl fragment but if you don't get a 
error message this might be something to think about in upcoming varnish 

Nevertheless I usually use the varnish CLI to load a new vcl in order to 
check the syntax
when loading (vcl.load) and switch back and forth in case of errors 
Usually the error message when getting a compilation error from a syntax 
in the vcl is quite self-explanatory.
