rewrite rules issue

[nicocolt]

Hello,

I have an issue with a rewrite rule for redirect to a subdomain. Here it
is:

if ($http_host = "subdomain.domain.fr") {
            rewrite ^(?!/\b(subpath|stats|error)\b)/(.*)$ /subpath/$2 last;
}

if in my browser i write:
host.domain.fr/admin (without last /), then I'm redirected to
host.domain.fr/host.domain/admin/ (with a 404 error of course)

But if i write:
host.domain/admin/ (with last /), then all works fine.

I don't understand what is the configuration issue. I want to have the same
behaviour with or without last /
Any help would be helpfull.

Best regards,
Nico
