LWP::UserAgent is Perl's standard HTTP client library. Connect to KnoxProxy with a single proxy() call and full HTTPS tunnel support.
Install the LWP modules from CPAN.
cpan install LWP::UserAgent LWP::Protocol::httpsConfigure LWP::UserAgent with KnoxProxy.
use LWP::UserAgent;
my $ua = LWP::UserAgent->new();
$ua->proxy(['http', 'https'], 'http://USER:PASS@gw.knoxproxy.com:7000');Send a GET request through the proxy.
my $response = $ua->get('https://httpbin.org/ip');
if ($response->is_success) {
print $response->decoded_content;
} else {
die $response->status_line;
}Target a specific country in the proxy username.
$ua->proxy(['http', 'https'], 'http://USER-country-de:PASS@gw.knoxproxy.com:7000');Use env_proxy to read from environment variables.
# Set in shell:
# export http_proxy=http://USER:PASS@gw.knoxproxy.com:7000
# export https_proxy=http://USER:PASS@gw.knoxproxy.com:7000
my $ua = LWP::UserAgent->new();
$ua->env_proxy;Add targeting headers and configure timeouts.
$ua->timeout(30);
$ua->default_header('X-KnoxProxy-Country' => 'jp');
my $response = $ua->get('https://httpbin.org/ip');
print $response->decoded_content;#!/usr/bin/env perl
use strict;
use warnings;
use LWP::UserAgent;
my $ua = LWP::UserAgent->new(
timeout => 30,
agent => 'KnoxProxy-Perl/1.0',
);
$ua->proxy(['http', 'https'], 'http://USER:PASS@gw.knoxproxy.com:7000');
my $response = $ua->get('https://httpbin.org/ip');
if ($response->is_success) {
print "Exit IP: " . $response->decoded_content . "\n";
} else {
die "Request failed: " . $response->status_line . "\n";
}Each request gets a new exit IP by default. For sticky sessions, use USER-session-{id} in the proxy URL (e.g., http://USER-session-myid:PASS@gw.knoxproxy.com:7000).
| Problem | Fix |
|---|---|
| 500 Can't connect to gw.knoxproxy.com:7000 | Install LWP::Protocol::https: cpan install LWP::Protocol::https. Verify port 7000 is not blocked by firewall. |
| 407 Proxy Authentication Required | Check username and password. URL-encode special characters (e.g., @ becomes %40 in the password). |
USER-country-de-city-berlin-session-profile07Order matters -- geo flags before the session flag. The session name is free text; use the profile ID so the mapping is self-documenting. Password stays as issued; no flags belong there. HTTP on :7000, SOCKS5 on :7001, same credentials.
Install LWP::Protocol::socks and set the proxy to socks://USER:PASS@gw.knoxproxy.com:7001.
Yes. Set http_proxy and https_proxy environment variables, then call $ua->env_proxy to pick them up automatically.
Each call to $ua->get() or $ua->post() gets a fresh exit IP by default. No extra configuration needed for rotation.
Mojo::UserAgent uses a different proxy API. Set $ua->proxy->http("http://USER:PASS@gw.knoxproxy.com:7000") for Mojo.
