HTTP Headers are converted to lowercase

[murer]

I know http spec says headers is case-insensitive, but I'm implementing a transparent proxy.
And as far as I know, some headers should not be modified by proxy.

http://tools.ietf.org/html/rfc2616
13.5.2 Non-modifiable Headers

Some features of the HTTP/1.1 protocol, such as Digest
Authentication, depend on the value of certain end-to-end headers. A
transparent proxy SHOULD NOT modify an end-to-end header unless the
definition of that header requires or specifically allows that.

It should be nice if I could retrieve original headers using http module because it does lots of hard work over sockets.

Use rawHeaders property added in 0.11: http://nodejs.org/docs/v0.11.14/api/http.html#http_message_rawheaders

Fast and precise.
