@ -49,13 +49,15 @@ The `map_remote` option lets you specify an arbitrary number of patterns that
define replacements within HTTP request URLs before they are sent to a server.
The substituted URL is fetched instead of the original resource
and the corresponding HTTP response is returned transparently to the client.
Note that if the original destination uses HTTP2, the substituted destination
needs to support HTTP2 as well, otherwise the substituted request may fail.

:flow-filter:regex:replacement
:flow-filter:regex:@file-path
:regex:replacement
:regex:@file-path

|flow-filter|regex|@file-path
|regex|replacement
|regex|@file-path
