post-process information from other web-server

I am looking for a snipped of code (in perl) for the following function:

- get information (whole page) i.e. http://www.imf.org/external/np/tre/sdr/drates/0701.htm and than it should save it as 0701.htm to the local drive.

Thanks

There is a very good article which describes in great detail how to do all of this (with the exception of writing the file to the local drive, which is trivial) at:

http://w3.stonehenge.com/merlyn/WebTechniques/col11.html

The script also does more, in that it processes the date in the file, but you can easily omit such processing.

An easy working example with an url included would help. (without the user agent funct. etc. )

======= geturl.pl

use Socket;

if ( $ARGV[0] ) { $_=$ARGV[0]; } else { die "Usage: geturl.pl url"; }

($notused,$host,$path,$name)= /(http:\/\/)([^\/]*)(.*\/)([^\/]*\w$)/;

print "Host: $host\nDocument: $path"."$name\nFile: $name\n";

$hostAddr = inet_aton($host) || die "Cannot lookup host $host";
socket( S, PF_INET, SOCK_STREAM, getprotobyname('tcp') ) || die "socket: $!";

while ($read > 0) { $read = sysread( S,$buff,10,length($buff)); }

open(OUT,">$name") || die "Error opening file: $name";

print OUT $buff;

Thank Paul!

What is ment with "ARGV"?
I get a Server Error with that:

#!/usr/bin/perl

# geturl.pl
###########

$host = "imf.org";
$path = "/external/np/tre/sdr/drates/";
$name = "0701.htm";

use Socket;

if ( $ARGV[0] ) { $_=$ARGV[0]; } else { die "Usage: geturl.pl url"; }

($notused,$host,$path,$name)= /(http:\/\/)([^\/]*)(.*\/)([^\/]*\w$)/;

print "Host: $host\nDocument: $path"."$name\nFile: $name\n";

$hostAddr = inet_aton($host) || die "Cannot lookup host $host";
socket( S, PF_INET, SOCK_STREAM, getprotobyname('tcp') ) || die "socket: $!";
connect( S, sockaddr_in(80,$hostAddr) ) || die "Unable to connect to $host port 80: $!";

$req="GET $path/$name\n";

syswrite( S, $req, length($req) );

$read=sysread( S, $buff, 1000);

while ($read > 0) { $read = sysread( S,$buff,10,length($buff)); }

open(OUT,">/web02/domain/html/source/$name") || die "Error opening file: $name";

print OUT $buff;

close(OUT);
