.SH DESCRIPTION
31 
.I Httpfile
32 
serves the web page specified by the URL
33 
.I url
34 
as a new file
35 
.I file
36 
in the directory
37 
.IR mtpt .
38 
The default
39 
.I file
40 
is the last path element of the URL,
41 
and the default
42 
.I mtpt
43 
is the current directory.
44 
.PP
45 
.I Httpfile
46 
does not download large files all at once.
47 
Instead, it requests 64-kilobyte blocks as they are
48 
needed to satisfy reads, caching a few blocks in memory at a time.
49 
.PP
50 
The
51 
.B -D
52 
and
53 
.B -d
54 
options enable a trace of the 9P traffic
55 
and general debugging messages.
56 
.PP
57 
The
58 
.B -s
59 
option causes
60 
.I httpfile
61 
to post the 9P service as
62 
.BI /srv/ srvname
63 
and disables the default mount.
64 
.PP
65 
The
66 
.B -x
67 
option specifies an alternate network directory
68 
.RI ( e.g.,
69 
.BR /net.alt ).
70 
.PP
71 
The
72 
.B -c
73 
option sets the number of file blocks kept cached in memory (default 32).
