Merry Christmas!

In my Perl helps Tomcat, I said that one thing I wanted to do was to use LWP::UserAgent, instead of forming HTPP request and doing socket calls myself.

But I am having some problem with the credentials() call with UserAgent. My expectation was that UserAgent will take whatever I specified with credentials() call, and add Authorization to the HTTP request, as what I did oringially. But either I had the wrong expectation, or I used credentials() in a wrong way, it does not work for me (my oringinal script works). Here is my attempt:

use LWP::UserAgent;
use HTTP::Request;

use strict;
use warnings;

my $ua = new LWP::UserAgent();
$ua->credentials("http://localhost:8080/", "Basic", "peip", "930612");
my $req;
if ($ARGV[0] eq "remove") {
    $req = new HTTP::Request("GET", "http://localhost:8080/manager/rem
+ove?path=/hello1");
} elsif ($ARGV[0] eq "install") {
    $req = new HTTP::Request("GET", "http://localhost:8080/manager/ins
+tall?path=/hello1&war=jar:file:/jwsdp/webapps/jwstutorial13/examples/
+web/hello1/dist/hello1.war!/");
}
my $res = $ua->request($req);
print $res->content();

Update:

Checked the source code of LWP::UserAgent. It looks like LWP::UserAgent does not send out Authorization in its first request. Instead it waits for the server to send back a response to challenge. Tomcat obviously responsed with the correct code: 401. I am now checking why LWP::UserAgent didn't response to 401.
