Add the target prefix mapping rule specified by

where each element is separated with whitespace.
.Pp
The prefix
.Pa from
of all matching targets, especially only of those requests for the canonical
virtual host
.Pa chost
when virtual hosts are specified, is then replaced with
.Pa to .
If no virtual hosts are given,
.Pa chost
is ignored.
.It Fl n Ar num
Set the maximum number of threads to
.Ar num .
The default is 512.
.It Fl p Ar port
In host mode, listen on port
.Ar port
for incoming connections.
In socket mode, use
.Ar port
for constructing proper virtual host
redirects on non-standard ports.
.It Fl U Ar file
Create the UNIX-domain socket
.Ar file ,
listen on it for incoming connections and remove it on exit.
.It Fl u Ar user
Set user ID when dropping privileges,
and in socket mode the user of the socket file,
to the ID of
.Ar user .
The default is "nobody".
.It Fl v Ar vhost
Add the virtual host specified by
.Ar vhost ,
which has the form
.Qq Pa chost regex dir [prefix] ,
where each element is separated with whitespace.
.Pp
A request matching the virtual host regular expression
.Pa regex
(see
.Xr regex 3 )
is redirected to the canonical host
.Pa chost ,
if they differ, using the directory
.Pa dir
as the root directory, optionally prefixing the target with
.Pa prefix .
If any virtual hosts are specified, all requests on non-matching
hosts are discarded.

.Sh CUSTOMIZATION
.Nm
can be customized by creating a custom config.h from config.def.h and
(re)compiling the source code. This keeps it fast, secure and simple.
