Validator Tips

• Validating the referring URL
• Validating password-protected documents
• Validating by FTP
• Choosing a DOCTYPE
• Using a custom DTD
• Using character encodings

Validating the Referring URL

Validation of the referring URL allows authors to conveniently use the same HTML as a validation link on any page:

<A
HREF="http://www.htmlhelp.com/cgi-bin/validate.cgi?url=referer">Validate
me</A>

To include the document's source, use the following:

<A
HREF="http://www.htmlhelp.com/cgi-bin/validate.cgi?url=referer&amp;input=yes">Validate
me</A>

One may also use "referrer" in place of "referer".

Validating Password-Protected Documents

To validate password-protected documents, use a URL of the form "http://user:pass@www.yourdomain.com/foo/bar.html". (While this is not a technically valid URL, it is accepted by the WDG HTML Validator for convenience.)

Validating by FTP

The validation by URL form supports both HTTP and FTP. For anonymous FTP, use a URL of the form "ftp://ftp.yourdomain.com/foo/bar.html". If you need a user name and password, use a URL of the form "ftp://user:pass@ftp.yourdomain.com/foo/bar.html".
