Reg: backend 'name' in VCL before going to origin

[Hardik]

Thanks Guillaume.

I am already using bereq.backend in v_b_f which is giving director name.
As you have pointed out,  I want 'exact' backend name inside director.
Also before sending to origin because want to set few  headers for origin
as per exact backend.
