Can a caddy act as a dynamic reverse agent?

[793162738 (蝶恋暗舞)]

*.aa.com {
    proxy *.bb.com
}

User realization:
wap.aa.com -> wap.bb.com
can caddy do that?

Such as:
{Caddyfile}
wap.aa.com {
proxy wap.bb.com
}
m.aa.com {
proxy m.bb.com
}

I’m afraid that’s not currently possible - there’s no way to take the matched wildcard from the site label.

There’s a couple of similar requests on the Github, #1894 and #1539, although they want to match the wildcard in the configured basepath rather than the site label.

See #1639 for the issue tracking the rewrite and eventual feature upgrades for the proxy directive.
