If you are using haproxy >=1.6, you might be able to do something like this:
acl no_redir %[req.redir] -m str NO_REDIR
http-request set-var(req.redir) \
%[hdr(host),map(/etc/haproxy/redirect_host.map,NO_REDIR)]
http-request redirect location %[req.redir] code 301 if !no_redir
This is completely made up and untested, but I hope you get the idea.
Avoids a second map lookup altogether, but also map lookups are quite fast,
so unless you map is huge you don't really need to worry about this. Also,
double negation, but this is just to give you some idea
Cheers,
Conrad
