    Boolean property.
    Whether or not to attempt to use the proxy setup from the underlying operating system. Defaults to false. Only considered if PROPERTY_PROXY_ENABLE_JVM_PROXY is false and PROPERTY_PROXY_HOST is not supplied. Due to how Java's java.net.useSystemProxies is handled, this may have limited effectiveness.

    java.net.useSystemProxies

    Defaults to true so that the Java standard way of setting proxies can be used. However if PROPERTY_PROXY_HOST is set that will always take priority when jclouds looks for a proxy. If this property is explicitly set false, then jclouds will not use a proxy irrespective of the java.net.* settings, unless PROPERTY_PROXY_HOST is set or PROPERTY_PROXY_SYSTEM is true.
