HTTP doesn't require the client browser to send any such
information to you, so there's no way you can be sure to get it.
The User-Agent header _may_ include some sort of platform
information. However, it may omit this information, or the
user can change it so it downright lies.
Therefore, unless you control the application running on the
client end (possible within a corporate environment, or if you're
running a rich client that just happens to use HTTP as its
communication transport; wherein your user-agent app on the
client side can send "X-*" extended headers that your server can
parse), you're at the mercy of your user to give you information
that you need/want. Compounding this problem, even *with*
benevolent user-agent strings, it won't include other
sys/os-module type information such the $PATH.
I'd suggest reading up on HTTP so you know what is and isn't
included in the protocol so you can set your expectations
according to its limitations.
