Did you find the option?

Well, a workaround that I sometimes use is to simply set a
req.backend, but not use it, like:

set req.backend = be_unused;
set req.backend = be_original;

Or

if (req.http.host == "veryfakeandinvalidhost") { set req.backend = be_unused; }

This way the backend is used by VCL but not used at all on the logic. :P
