handle
Evaluates a group of directives mutually exclusively from other handle
blocks at the same level of nesting.
In other words, when multiple handle
directives appear in sequence, only the first matching handle
block will be evaluated. A handle with no matcher acts like a fallback route.
The handle
directives are sorted according to the directive sorting algorithm by their matchers. The handle_path
directive is a special case which sorts at the same priority as a handle
with a path matcher.
Handle blocks can be nested if needed. Only HTTP handler directives can be used inside handle blocks.
Syntax
handle [<matcher>] {
<directives...>
}
- <directives...> is a list of HTTP handler directives or directive blocks, one per line, just like would be used outside of a handle block.
Similar directives
There are other directives that can wrap HTTP handler directives, but each has its use depending on the behavior you want to convey:
-
handle_path
does the same ashandle
, but it strips a prefix from the request before running its handlers. -
handle_errors
is likehandle
, but is only invoked when Caddy encounters an error during request handling. -
route
wraps other directives likehandle
does, but with two distinctions:- route blocks are not mutually exclusive to each other,
- directives within a route are not re-ordered, giving you more control if needed.
Examples
Handle requests in /foo/
with the static file server, and other requests with the reverse proxy:
example.com {
handle /foo/* {
file_server
}
handle {
reverse_proxy 127.0.0.1:8080
}
}
You can mix handle
and handle_path
in the same site, and they will still be mutually exclusive from each other:
example.com {
handle_path /foo/* {
# The path has the "/foo" prefix stripped
}
handle /bar/* {
# The path still retains "/bar"
}
}
You can nest handle
blocks to create more complex routing logic:
example.com {
handle /foo* {
handle /foo/bar* {
# This block only matches paths under /foo/bar
}
handle {
# This block matches everything else under /foo/
}
}
handle {
# This block matches everything else (acts as a fallback)
}
}
