+---
+
+# handle_path
+
+Same as the [`handle` directive](/docs/caddyfile/directives/handle), but implicitly strips the matched path prefix.
+
+Handling a request matching a certain path (while stripping that path from the request URI) is a common enough use case that it has its own directive for convenience.
+
+
+## Syntax
+
+```caddy-d
+handle_path <path_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_path block.
+
+Note that only a single path matcher is accepted and required; you cannot use other kinds of matchers with handle_path.
+
+## Examples
+
+This configuration:
+
+```caddy-d
+handle_path /prefix/* {
+	...
+}
+```
+
+is effectively the same as this:
+
+```caddy-d
+handle /prefix/* {
+	uri strip_prefix /prefix
+	...
+}
+```
+
+but the `handle_path` form is slightly more succinct.
