Hi,

I hope I got you right. You want to read a file not located on the server the script is running on, but accessable via HTTP? If that's what you want, use the libwww-perl package.
Here's a small example:

Code

#!/bin/perl -w 
use LWP::Simple; 
  
$url  = "http://www.path.to/my/file"; 
$file = get($url); 
  
# now, do whatever you like with file

This will read the file located under any URL $url into the scalar $file. Hope this is near to what you expected.

Re: simple question [In reply to]	Can't Post

hey
I was wondering you can get anything from any url correct? Well what would it return if you linked it to get something from another cgi you have on a different server. Will it give you the script or the results of activating the cgi. If people can get the script is there anyway to block that?

Thanks :)

Trying to get a cgi-script via HTTP always results in the HTTP server executing the script. Trying to get a file using LWP is in no way different from a browser trying to get that file. So there's no need to block Wink

Thanks :)

How about installing it? If you don't have full access to the server, just install it in your cgi-bin directory. I guess it should work, but I'm not 100% sure.

I don't know. But you can find out where perl searches for its libraries: the paths are all stored in the @INC array. You can now use perl to execute an ll on each of these directories and print it to an HTML page. This should give you a listing of all perl include directories.

P.S. If you don't feel able to build a script from the above information, tell me and I'll see if I can do a quick hack.

Download the package from CPAN, unpack it, and upload the contents of the lib directory to your cgi-bin directory. This should be all.

No, just put it plain in the cgi-bin directory.
