The "if" and "return" keywords are all lower-case.

If there's a syntax error, you get an error message from the VCL
compiler. The messages are not always very explanatory, but mostly
they are, and you should always send along the contents of the error
message when you're asking for help. (You might find that it explains
the problem well enough that you don't have to ask in the first place.)

Also: this exact code is in builtin.vcl for vcl_recv (of course with
the correct syntax for the keywords). Can you just let your own
vcl_recv drop into the built-in version? If your own VCL subroutines
end at any point without calling return(), then Varnish goes on to
execute the built-in version. If you can let that happen, then you
don't need to do this yourself at all. If this is *only* thing you
want in vcl_recv, then you don't need to write your own vcl_recv, just
let builtin.vcl do the job.


HTH,
Geoff
