Reading a file on another server

I want to read a file on any server and do something with the text it contains. I know there are a similar question available by searching (Q.10256678) but the source code provided there wont work for me. It fails on the line "use LWP::Simple;", giving me no specific error message, just a notification that the server cant execute the file. If anyone knows how this can be fixed or knows another way to do the thing I want to do, please let me know.

I know that this can be done by using sockets, but I dont know exactly how to do it. Could anyone provide some source code on how to open a socket to an URL and putting that URL's data in a variable $data, or at least tell me how to do it?

I hope the code-sample below will solve your problems. - I took it from "Perl Cookbook" and modified just the last few lines. - It works for me.

test the script by saving it to a file ( and run it by calling "perl"

---- script sarts here----

#!/usr/bin/perl -w
# titlebytes - find the title and size of documents
use LWP::UserAgent;
use HTTP::Request;
use HTTP::Response;
use URI::Heuristic;
my $raw_url = shift or die "usage: $0 url\n";
my $url = URI::Heuristic::uf_urlstr($raw_url);
$| = 1;                                  # to flush next line
printf "%s =>\n\t", $url;
my $ua = LWP::UserAgent->new();
$ua->agent("Schmozilla/v9.14 Platinum"); # give it time, it'll get there
my $req = HTTP::Request->new(GET => $url);
                                         # perplex the log analysers
my $response = $ua->request($req);
if ($response->is_error()) {
     printf " %s\n", $response->status_line;
 } else {
     my $content = $response->content();
     printf $DATA;
Program uses unit "Simple" (file in subdirectory LWP), but cann't find it! To fix this problem you need find this file and place it in corresponding subfolder (or change path).

I have found the file "" and it was located in the subdirectory LWP, like you said, so I assume that the path is correct.

Can you post me this program (with by email?
dedsiAuthor Commented:
Ok, it works but where do I put the URL I wish to "visit" in the source code? I want this to run from a homepage and I want to decide which URLs I might be able to visit from within my source (or from a Query string).
sorry ... that's no big deal:

you just have to watch the line:
my $raw_url = shift or die "usage: $0 url\n";

=> if you want to assign the variable $raw_url an URL within your perl-script that can simply be done by:

my $raw_url = "";


my $my_address = "";
my $raw_url = $my_address;

.... that should work.

have you tried it from a web browser? I cant get it to work for me from a browser but I can run it from the command line (perl ...). I get a "500 Server Error" message.
.. your "500 Server Error" has nothing to do with the question you've asked!!! That means that if the program runs in a command line it should work as a cgi-script too. - If it doesn't you have some kind of syntax-error .. usually some misplaced quotation marks or some "special-characters" .. like "@", "%", or things like that .... but that syntax error has nothing to do with the principle of fetching files from remote severs!!

.... e.g:
if you fetch the content of some remote-html file it usually contains some "special-characters" like the above mentioned "@" or quotationmarks itself ... if you want to print that out into in a browser with e.g.
you will of course get errormessages!!!!!!

=> you have to parse the content of the remote file first and replace all non-allowed characters!!!

.... but that has nothing to do with the question you've asked :-)
. I just want to say that I find the grade you gave me not correct ... you wanted a solution for your specific problem - I gave you the exact WORKING answer .. so I can't understand why you've graded me with "C"....
dedsiAuthor Commented:
Okay, when I come to think about it, your answer are actually what I asked for. I guess I put the "low" grade because I couldnt get it to work in a web browser and I thought I had specified that in the question, but I never did. Im sorry. So, what grade do you want (think your answer are worth)? Is there any way to change it by now?
