proxy setup

all_proxy=proxy.company.com:8080

**more detail please ref curl document:
The proxy environment variable contents should be in the format "[protocol://][user:password@]machine[:port]". Where the protocol:// part is simply ignored if present (so http://proxy and bluerk://proxy will do the same) and the optional port number specifies on which port the proxy operates on the host. If not specified, the internal default port number will be used and that is most likely not the one you would like it to be.

There are two special environment variables. 'all_proxy' is what sets proxy for any URL in case the protocol specific variable wasn't set, and 'no_proxy' defines a list of hosts that should not use a proxy even though a variable may say so. If 'no_proxy' is a plain asterisk ("*") it matches all hosts.
