Patching servers through proxy
If your servers don't have direct Internet access but can gain access to the Internet using proxy, the configuration is not that different. KernelCare can pick up standard environment variables for a proxy.

# export http_proxy=http://proxy.domain.com:port # export https_proxy=http://proxy.domain.com:port
