mod_http_oauth2: Skip consent screen if requested by client and same scopes already granted
This follows the intent behind the OpenID Connect 'prompt' parameter
when it does not include the 'consent' keyword, that is the client
wishes to skip the consent screen. If the user has already granted the
exact same scopes to the exact same client in the past, then one can
assume that they may grant it again.

# mod_ogp This module adds [Open Graph Protocol](https://ogp.me) metadata to URLs sent inside a MUC. With mod_ogp enabled, when a user sends a URL in a MUC (where the message has its `id` equal to its `origin-id`), the module calls the URL and parses the result for `<meta>` html tags that have any `og:...` properties. If it finds any, it sends a [XEP-0422 fastening](https://xmpp.org/extensions/xep-0422.html) applied to the original message that looks like: ```xml <message id="example" from="chatroom@muc.example.org" to="user@chat.example.org/resource"> <apply-to xmlns="urn:xmpp:fasten:0" id="origin-id-X"> <meta xmlns="http://www.w3.org/1999/xhtml" property="og:title" content="The Rock"/> <meta xmlns="http://www.w3.org/1999/xhtml" property="og:url" content="https://www.imdb.com/title/tt0117500/"/> <meta xmlns="http://www.w3.org/1999/xhtml" property="og:image" content="https://ia.media-imdb.com/images/rock.jpg"/> </apply-to> </message> ``` The module is intentionally simple in the sense that it is basically a transport for https://ogp.me/ Configuration ------------- You can present an allowlist or denylist of domains for which OGP metadata will be fetched via the `ogp_domain_allowlist` and `ogp_domain_denylist` settings repectively. For example: ```lua Component "muc.example.org" "muc" modules_enabled = { "ogp" } ogp_domain_allowlist = { "prosody.im" } ```
