Functions

func GetAuthHeader

func GetAuthHeader(u *url.URL) (string, error)

GetAuthHeader returns the Authorization header value to send to proxy u.

func InvalidateCache

func InvalidateCache()

InvalidateCache invalidates the package-level cache for ProxyFromEnvironment.

It's intended to be called on network link/routing table changes.

func ProxyFromEnvironment

func ProxyFromEnvironment(req *http.Request) (ret *url.URL, _ error)

ProxyFromEnvironment is like the standard library's http.ProxyFromEnvironment but additionally does OS-specific proxy lookups if the environment variables alone don't specify a proxy.

func SetSelfProxy

func SetSelfProxy(addrs ...string)

SetSelfProxy configures this package to avoid proxying through any of the provided addresses–e.g. if they refer to proxies being run by this process.

func SetTransportGetProxyConnectHeader

func SetTransportGetProxyConnectHeader(tr *http.Transport)

SetTransportGetProxyConnectHeader sets the provided Transport's GetProxyConnectHeader field, and adds logging of the received response.
