HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as percent-encoding.
Bad value “X” for attribute “href” on element “a”: User or password contains an at symbol ("@") not percent-encoded.
The at symbol (@) should be percent-encoded as %40 in order to include it at an href attribute.
