+version_added: '2.8'
+short_description: Manages proxy settings for WinHTTP
+description:
+- Used to set, remove, or import proxy settings for Windows HTTP Services
+  C(WinHTTP).
+- WinHTTP is a framework used by applications or services, typically .NET
+  applications or non-interactive services, to make web requests.
+options:
+  bypass:
+    description:
+    - A list of hosts that will bypass the set proxy when being accessed.
+    - Use C(<local>) to match hostnames that are not fully qualified domain
+      names. This is useful when needing to connect to intranet sites using
+      just the hostname.
+    - Omit, set to null or an empty string/list to remove the bypass list.
+    - If this is set then I(proxy) must also be set.
+    type: list
+  proxy:
+    description:
+    - A string or dict that specifies the proxy to be set.
+    - If setting a string, should be in the form C(hostname), C(hostname:port),
+      or C(protocol=hostname:port).
+    - If the port is undefined, the default port for the protocol in use is
+      used.
+    - If setting a dict, the keys should be the protocol and the values should
+      be the hostname and/or port for that protocol.
+    - Valid protocols are C(http), C(https), C(ftp), and C(socks).
+    - Omit, set to null or an empty string to remove the proxy settings.
+  source:
+    description:
+    - Instead of manually specifying the I(proxy) and/or I(bypass), set this to
+      import the proxy from a set source like Internet Explorer.
+    - Using C(ie) will import the Internet Explorer proxy settings for the
+      current active network connection of the current user.
+    - Only IE's proxy URL and bypass list will be imported into WinHTTP.
+    - This is like running C(netsh winhttp import proxy source=ie).
+    - The value is imported when the module runs and will not automatically
+      be updated if the IE configuration changes in the future. The module will
+      have to be run again to sync the latest changes.
+    choices:
+    - ie
+    type: str
+notes:
+- This is not the same as the proxy settings set in Internet Explorer, also
+  known as C(WinINet); use the M(win_inet_proxy) module to manage that instead.
+- These settings are set system wide and not per user, it will require
+  Administrative privileges to run.
