For example:

map $request $testvar {
        default                                 0;
        ~*montytest                           1;
}

if ($testvar) { return 412; }

[20/Jun/2014:xx:xx:20 +0200] 69.64.xxxx:52393 - - "GET /montytest/
HTTP/1.1"
412 712 "-" "Mozilla/5.0........

[20/Jun/2014:xx:xx:29 +0200] 115.254.xxxx:59855 - - "HEAD /montytest/
HTTP/1.1" 400 0 "-" "-" "-" -

Why does a GET work but not a HEAD ??

It looks like the HEAD request was invalid, and hence 400 was
returned before any further processing.  The reason why 400 was
returned should be in error log at info level.

The log entries are both in access.log, nothing in error.log, maybe a
try_files thing ? though the IF is after try_files and works for a GET.

Note that you have to configure error_log to log "info" level
messages.  By default, logging level is "error".

It was a malformed request so a 400 is correct, a valid HEAD in this
case
does return a 412.
