provides a handler to protect a request to internal servers.
It's useful to implement OpenID servers, crawlers, etc.

make_paranoid($ua[, $dns]);
Make your LWP::UserAgent instance to paranoid.
The $dns argument is instance of Net::DNS::Paranoid. It's optional.
FAQ
How can I timeout per request?
Yes, LWP::UserAgent does not timeouts per request.
I think it's my job. But LWPx::ParanoidAgent do this.
You can do this by following form using alarm():
my $res = eval {
local $SIG{ALRM} = sub { die "ALRM\n" };
alarm(10);
my $res = $ua->get($url);
alarm(0);
$res;
};
$res = HTTP::Response->new(500, 'Timeout') unless $res;
And I recommend to use Furl. Furl can handle per-request timeout
cleanly.

SEE ALSO
LWPx::ParanoidAgent have same feature as this module. But it's not
currently maintain, and it's too hacky. LWPx::ParanoidHandler uses
handler protocol provided by LWP::UserAgent, it's more safety.
This module uses a lot of code taken from LWPx::ParanoidAgent, thanks.
