; ======================
; HTTP client signatures
; ======================

; Safari and Firefox are frequently seen using HTTP/1.0 when going through
; proxies; this is far less common for MSIE, Chrome, etc. I wildcarded some of
; the signatures accordingly.
;
; Also note that there are several proxies that mess with HTTP headers for no
; reason. For example, BlueCoat proxy appears to change 'keep-alive' to
; 'Keep-Alive' for a tiny percentage of users (why?!).
