hi all,
I've read through several similar posts regarding this problem but still haven't been able to find an answer for my situation. I wanted to clarify that my system doesn't have any proxy setting. my system is Linux. So I have a simple program to consume a restful webservice.

#!/usr/local/bin/perl -w
use strict;
use LWP::UserAgent;
my $ua = LWP::UserAgent->new;
my $req = HTTP::Request->new(GET => $url);
##add some headers here##
my $res = $ua->request($req);

When i ran this code, it timed out( i increased timeout still not solving the issue). I was able to consume this url with a PHP script i wrote. I also used other 3rd party restful api(firefox addon, java app) on the same url with no issue. so i took it further by setting up wireshark and ran the perl script. when i looked at the packets, it seemd like all the relevant data was passed back to my system. But some how the LWP library(/usr/local/share/perl5/LWP/Protocol/http.pm at function "can_read") was not able to get the end of message. Below is the Dumper of the Response object and handler from UserAgent.
