This service tunnels HTTP requests and changes the MIME type of
text/html resources to
application/xhtml+xml or any other MIME type. This allows accurate testing with XHTML user agents.
When an input document is not well-formed, the unmodified source is output. An XHTML user agent will then detect the well-formedness violation. Otherwise, a comment
<!-- XHTML Proxy has successfully processed this page. --> is added at the end of the page.
Testing XHTML documents in XHTML user agents is important as there are subtle differences between HTML and XHTML:
document.write()is not supported in XHTML
table > tbody > trwork in HTML, but not in XHTML
might not get resolved by XHTML user agents
To avoid excessive traffic at w3.org, some DTD URLs (such as
http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd) are rewritten to point to my own server.
Don't hesitate to send your comments to Christoph Schneegans (Christoph@Schneegans.de).
HTTP requests from this service always contain the header
