This particular case actually doesn't bother me in particular. It may
be fine for "/%" to be a 400 rather than a 404.
My particular case involved needing to process mal-formed query strings
sent by third parties. I had no control over these third parties. I
_needed_ to be able to process query strings that included un-escaped
ampersands and such. Yes, the third party sending me this information in
a query string was doing it in a way that was illegal and violated
standards, but they are more powerful than I, and I can not make them
change their behavior, and I need to handle those URLs anyway.
I took care of it with a rewrite on the apache end before it reached
mongrel though. This ended up being somewhat more complicated then I
hoped it would be becuase of Apache's weird and unpredictable behavior
when it came to escaping, but now that I have it working, it works out.

If you append an extra percent sign to a URL that gets passed to
mongrel, it will return a Bad Request error. Kind of odd that
"http://localhost/%"; causes a "Bad Request" instead of a "Not Found"
error.
Here is the error from the mongrel log:
HTTP parse error, malformed request (127.0.0.1):
#<Mongrel::HttpParserError: Invalid HTTP format, parsing fails.>
I'm using Nginx in front of mongrel. I understand this is a bad URL,
but is there anyway to have mongrel ignore lone percent signs? Or
perhaps a Nginx rewrite rule that will encode extraneous percent signs?
Out of curiousity, why does mongrel's handling of this case bother you?
Looks like entirely standard behaviour, see

(All produce status 400)
