This library finds the public address of the running server. This can be used to construct URLs that are visible from anywhere on the internet. This module was introduced to deal with OpenID, where a request is redirected to the OpenID server, which in turn redirects to our server (see http_openid.pl).
The address is established from the settings
http:public_port if provided. Otherwise it is deduced from the request.
- http_public_url(+Request, -URL) is det
- True when URL is an absolute URL for the current request. Typically, the login page should redirect to this URL to avoid losing the session.
The following predicates are exported, but not or incorrectly documented.
