 In order to hidden the real path, I send the png file via CGI, e.g.

##############

print "Content-type:image/png\n\n";
my $file = "test.png";

open INPUT_FILE, "$file" or die "Couldn't open file: $!";
while( sysread(INPUT_FILE, $data, 10240) ) {
        print $data;
}
close FILE;

##############

Any faster/better method?

Thanks.

An alias (HTTP server directive).

Hi,

A path is mapped to many files, so the real file is only know when
client request for the page.

I have heard something like x-sendfile but we don't have this option
to use, so I must send thru perl.

Thanks.

Howard

Take a step back and do some introspection on why you want to hide the
real path in the first place.
