.SH DESCRIPTION
|
|
.I Httpfile
|
|
serves the web page specified by the URL
|
|
.I url
|
|
as a new file
|
|
.I file
|
|
in the directory
|
|
.IR mtpt .
|
|
The default
|
|
.I file
|
|
is the last path element of the URL,
|
|
and the default
|
|
.I mtpt
|
|
is the current directory.
|
|
.PP
|
|
.I Httpfile
|
|
does not download large files all at once.
|
|
Instead, it requests 64-kilobyte blocks as they are
|
|
needed to satisfy reads, caching a few blocks in memory at a time.
|
|
.PP
|
|
The
|
|
.B -D
|
|
and
|
|
.B -d
|
|
options enable a trace of the 9P traffic
|
|
and general debugging messages.
|
|
.PP
|
|
The
|
|
.B -s
|
|
option causes
|
|
.I httpfile
|
|
to post the 9P service as
|
|
.BI /srv/ srvname
|
|
and disables the default mount.
|
|
.PP
|
|
The
|
|
.B -c
|
|
option sets the number of file blocks kept cached in memory (default 32).
|
|
