Header names have been capitalized, and may not appear exactly as transmitted by your browser.
This should not make a difference to servers and clients, because the HTTP specification specifically states that HTTP headers should be case-insensitive
Hop-by-hop headers, as defined by RFC 2616, are not displayed
We have a secure endpoint now as well: https://xhaus.com/headers
We've noticed that some folks use this facility to test how query strings are encoded in requests. So we now display those as well
If you discover any issues with this facility, we're reachable on headers__at__xhaus_com
