Article 187

URL that contains "@" in password

From the RFC 1738:

"...Only alphanumerics [0-9a-zA-Z], the special characters "$-_.+!*'()," [not including the quotes - ed], and reserved characters used for their reserved purposes may be used unencoded within a URL."

You have to hex encode the @ in the URL:
user: myuser
password: h@t
host: myhost

To url => hex encode unsafe characters =>
