PROC NEW(func<HTTP.Context => bool> func, string to) @public

Create a new login servlet, using func to check if the user is logged in and redirect to URL to if not.

The func must return TRUE when the user is already logged in, e.g. by checking a cookie. In that case the Servlet $serve() method will return FALSE.

By default works for all paths except to. Call $setAllPaths(FALSE) and $addPath() to change that.

Remember to add this Servlet before any Servlet that requires login.

FUNC $serve(HTTP.Context context) bool @replace @public

Handle a redirect request.

FUNC $setPostHandler(func<HTTP.Context => int> func) HTTP.LoginServlet @public

Set a function to handle POST requests.

Redirecting POST request doesn't really work.

The func argument will be invoked when not logged in for a POST request. It must return the HTML status code.

Returns the object for chaining.

PROC $setResponseCode(int code) @public

Change the default 301 response code into code.
