Can I disable the auto redirect of http to https?

Help
1

In some cases, my users set up their domains under our name servers but still don’t configure them inside our product.
So we like to show them a page under the “HTTP” that explains the issue.

Just use a clear HTTP address as the site address:

http://example.com {
    reverse_proxy ....
}

Automatic HTTPS is enabled if your site’s address contains a hostname or IP address. This behavior is purely implicit, however, so it never overrides any explicit configuration. For example, if the site’s address is http://example.com , auto-HTTPS will not activate because the scheme is explicitly http://

But I don’t know what will be the domain.
I need something like:

http://* {
    reverse_proxy ....
}

If you don’t know the domain name, you can try http://0.0.0.0, I’m not sure if this works; to be honest, I’m very curious about this demand… :crazy_face:

In Caddy 0.11 I had this option

Just use a site block using http:// which will match all hostnames.

http:// {
	respond "No redirect"
}

Since v2.4.0, this will not prevent HTTP->HTTPS redirects for domains explicitly configured in Caddy, but this will prevent HTTP->HTTPS redirects for on-demand domains that Caddy does have certificates for.

In general, to turn off all HTTP->HTTPS redirects, you can use this global option:

{
	auto_https disable_redirects
}

My little question: Is there a way to implement Nginx’s default_server directive?

When requesting the Caddy default IP, respond to a specific page (do not use http://CADDY_SEVER_IP).
