Well, I've got another question.

Now that I've got my code working it would seem I am not doing something as far as deleting connections. I am seeing the memory usage continue to climb with time. I understand that a connection will use an amount of memory equal to it's total size but shouldn't that memory be released back to the pool once I write the file? Am I supposed to delete each connection in my callback after I save it?

I am really just using the example code with a couple lines to save the content as a file. 

#!/usr/bin/perl
use strict;
use Net::Pcap;
use Sniffer::HTTP;
my $VERBOSE = 1;
  
  my $sniffer = Sniffer::HTTP->new(
  callbacks => {
      request  => sub { my ($req,$conn) = @_; print $req->uri,"\n" if 
+$req },
      response => sub { my ($res,$req,$conn) = @_; 
         print $req->uri,"\n" if ($req);
         return if (length $res->content == 0);
                (my $filename = $req->uri)=~s/.*\///;
        open (FILE,">",$filename);
        print FILE $res->content;
        close FILE;
        },
         
   log      => sub { print $_[0] if $VERBOSE },
   tcp_log  => sub { print $_[0] if $VERBOSE > 1 },
  },
  timeout => 1*60, # seconds after which a connection is considered st
+ale
   stale_connection => sub { my ($s,$conn,$key) = @_;
       my %test=%$conn;
       $conn->log->("$key is stale.");
       $s->remove_connection($key);
   },
);
   $sniffer->run('eth0'); # uses the "best" default device

I see how the stale_connection callback does this but the request and response callbacks do not get the information that stale_connection uses to delete the connection. Or am I supposed to be creating a new $sniffer->run() for each connection?

I have certainly missed something.

Thanks again for all your help.
