But your example did conform to the UNIX path/file syntax, so there's no
reason for it to be bounced.

For an example of the pitfalls of using PATH_INFO for random data; consider
trying to send the string "/../" as part of the PATH_INFO.


Almost every server (and many browsers) will give you
PATH_INFO = /adir'
and I don't think this is particularly bad behaviour.

Even URL-encoding the .. doesn't help;'/%2e%2e/astr'
gives the same result. This may be a bug though. (Roy?)
