Exclude path from redirect

[humbleton]

The problem I’m having:

Hey Caddy community.

I have the following in my Caddyfile:

www.mydomain.com {
    handle /google1234567890.html {
         file_server
    }

    encode zstd gzip
    reverse_proxy my-frontend:3000

    import redirects/myredirects

}

in redirects/myredirects there is a rule that redirects paths with a .html suffix to the same path without it:
@htmlSuffix path_regexp htmlSuffix ^(.*).html$
redir @htmlSuffix {http.regexp.htmlSuffix.1}

Now i would like to exclude the /google1234567890.html path, since it’s a verification file for google that needs to be accessible WITH .html suffix.

How can this be achieved?
I’ve tried regex with negative lookahead, but that doesn’t seem to be supported

Caddy version:

2.8

Following combination of request matchers solved my problem:

@htmlRedirects {
    not {
        path /google1234567890.html
    }
    path_regexp htmlSuffix ^(.*)\.html$
}
redir @htmlRedirects {re.htmlSuffix.1}
