[pm-h] Is this possible?

[Mark Allen]

I'd suggest in "Modern Perl" you'd want to create some kind of persistent web service to replace the "validator.cgi" using Dancer (or some other $WEB_FRAMEWORK)

A really simple one would be something like

https://gist.github.com/3177150


On the front side you could have another Dancer app that shows the form - a really concise example is here in my Dancer tutorial at line 83


https://bitbucket.org/mrallen1/dancr/src/7ca51c18f350/dancr.pl#cl-83


And instead of using the code that's in that sub, you could simple do something like

my $req = HTTP::Request->new(
  'POST', 
  'http://localhost:5000/auth', 
  { 
    username => params->{username}, 
    password => md5_hex(params->{'password'} 
  }
);

my $response = $ua->request($req)

if ( $response->is_success ) {
  # in like flynn
  # do stuff here
} else {
  # "not authorized"
}

If you want to get ridiculously fancy, you could check out something like AnyEvent::HTTP to make asynchronous auth requests.[1]

--Mark

[1] But you might not want to given that the AnyEvent learning curve can feel steep and the author of AnyEvent is kind of a jerkface at times.

Fraser,

I think you just need to use the CGI module.

You'll need some notion of a session, as well.
