SpiderOakのHTTPプロキシを環境変数から設定する

More than 5 years have passed since last update.

SpiderOakのFAQ より。

If you are executing SpiderOak from the command line, this can be arranged by setting the Environment variable SPIDEROAK_HTTP_PROXY using this format:

http://proxy_hostname/
If your proxy server requires authentication, you may specify it this way:
http://username:password@proxy_hostname/

Windows版でも、この環境変数SPIDEROAK_HTTP_PROXY は有効。
