One of the most damanging accusations ever launched against any
programming language was in one of the historical attacks on PASCAL.
I can't remember who exactly wrote it, but the operative sentence was:
"Worst of all, there is no escape."
VCL has a planned escape mechanism, but I have not said anything
about it yet, wanting to see if anybody actually needed it.
The concept is that hat arbitrary C-code can be inserted into VCL
programs, possibly something like:
sub vcl_recv {
C{
{
char *p = VRT_GetHdr(sp, 1, "\005Host:");
...
}
}C
}
That should allow you to do what your patch does, entirely
from within VCL.

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.
