I wouldn't agree there:
http://www.example.com/file with spaces.png [1]

returns invalid method: 400. I think the entire 4xx and 5xx family should 
return false.

[1] I know the url is invalid, but if you wanna do syntax checking on urls, 
then you're in for a treat, especially when the url contains double-byte 
characters.

As for 30[12], what happens when the refered document does not exist?
Symlinks have a maximum number of links and return ELOOP. Does the same apply 
to 302 and what is the value of MAXSYMLINKS (sys/param.h) in that case?
