Now any of the following env variables may be exported before using
cmk with any http/https proxy:

export http_proxy='http://user:password@server:3128'
export https_proxy='http://user:password@server:3128'
export HTTP_PROXY='http://user:password@server:3128'
export HTTPS_PROXY='http://user:password@server:3128'

Or, run cmk like following:

HTTP_PROXY="http://IP:port" cmk
