# Documentation

data Proxy #

HTTP proxies (or not) are represented via `Proxy`, specifying if a proxy should be used for the request (see `setProxy`)

Constructors

NoProxy | Don't use a proxy.
Proxy String (Maybe Authority) | Use the proxy given. Should be of the form "http://host:port", "host", "host:port", or "http://host". Additionally, an optional `Authority` for authentication with the proxy.

noProxy :: Proxy #

fetchProxy :: Bool -> IO Proxy #

`fetchProxy flg` gets the local proxy settings and parse the string into a `Proxy` value. If you want to be informed of ill-formed proxy configuration strings, supply `True` for `flg`. Proxy settings are sourced from the `HTTP_PROXY` environment variable, and in the case of Windows platforms, by consulting IE/WinInet's proxy setting in the Registry.

parseProxy :: String -> Maybe Proxy #

`parseProxy str` translates a proxy server string into a `Proxy` value; returns `Nothing` if not well-formed.
