WebKit is has a broken Accept header, it puts text/xml and application/xml
first which breaks Catalyst::Action::REST’s default configuration and makes
the idea of being able to dispatch html/xhtml different from XML difficult at
The reason it turns out is that the webkit developers cargo-culted from
Firefox, and someone in 2007 provided a patch. The
response to the patch is “buh buh Firefox is doing it!”. When I tried to
add the comment below I discovered that their bugzilla required me to log in
and didn’t appear to have an option for OpenID. Because I’m loath to create
yet another account to file a single comment on a bug I’ve included the text
Firefox (3.1 beta 2 at least) is no longer sending this Accept headers.
Currently writing a REST-ful interface that renders XML different from
XHTML/HTML at the same URI is difficult (requires us to browser sniff and do
we really want to go back to that?) because Webkit based browsers will all
send then wrong Accept headers first. I actually ran into this while writing
an app that targets Android/iPhone and I had to disable my XML rendering code
(luckily it was a stub and not a required feature).
Last the logic “Firefox does this” is a fallacy that I thought most people
were taught better by their mothers at an early age … if Firefox were to
jump off a bridge should WebKit too?
