FYI: RFC 1738 -- Uniform Resource Locators (URL) -- December 1994 <extract> 3.1. Common Internet Scheme Syntax While the syntax for the rest of the URL may vary depending on the particular scheme selected, URL schemes that involve the direct use of an IP-based protocol to a specified host on the Internet use a common syntax for the scheme-specific data: //<user>:<password>@<host>:<port>/<url-path> Some or all of the parts "<user>:<password>@", ":<password>", ":<port>", and "/<url-path>" may be excluded. The scheme specific data start with a double slash "//" to indicate that it complies with the common Internet scheme syntax. The different components obey the following rules: user An optional user name. Some schemes (e.g., ftp) allow the specification of a user name. password An optional password. If present, it follows the user name separated from it by a colon. The user name (and password), if present, are followed by a commercial at-sign "@". Within the user and password field, any ":", "@", or "/" must be encoded. </extract> -- Hassan Schroeder ----------------------------- hassan at webtuitive.com Webtuitive Design === (+1) 408-938-0567 === http://webtuitive.com dream. code.
