Hello, there are multiple ways to insert HTML and scripting into the validator... * Simple querystring: http://validator.w3.org/check?uri=http://<script>alert("boo")</script> * Character encoding HTTP header: Returning "Content-type: text/html; charset=<script>...</script>" http://validator.w3.org/check?uri=http://tom.me.uk/2002/9/val.asp * Server HTTP header - "Server: <script>...</script>" * Content-length HTTP Header - "Content-length: <script>...</script>" All of these should have the HTML escaped before outputting.
