I'm sure this send_request_raw() works perfect the way it is. Would you like to try a slightly cleaner way to write this?

```ruby
send_request_cgi({
	'uri'       => '/+webvpn+/index.html',
	'method'    => 'POST',
	'agent'     => 'ASDM/ Java/1.6.0_65',
	'ctype'     => 'application/x-www-form-urlencoded; charset=UTF-8',
	'cookie'    => 'webvpnlogin=1; tg=0DefaultADMINGroup',
	'vars_post' => {
		'username' => user,
		'password' => pass,
		'tgroup'   => 'DefaultADMINGroup'
	}
})
```
