Proposed patch to fix an issue on the REQUEST_PROTOCOL variable and log data:

msc_process_uri() appends the string "HTTP/" to http_version probably because the Nginx connector doesn't.

The problem happens due the fact that in Apache, the request_rec:::protocol data field returns the protocol string in the form of "HTTP/1.1".

not sure it's the most elegant fix, but it worked for me.

Merged. Thanks.
