mod_http_oauth2: Implement stateless dynamic client registration Replaces previous explicit registration that required either the additional module mod_adhoc_oauth2_client or manually editing the database. That method was enough to have something to test with, but would not probably not scale easily. Dynamic client registration allows creating clients on the fly, which may be even easier in theory. In order to not allow basically unauthenticated writes to the database, we implement a stateless model here. per_host_key := HMAC(config -> oauth2_registration_key, hostname) client_id := JWT { client metadata } signed with per_host_key client_secret := HMAC(per_host_key, client_id) This should ensure everything we need to know is part of the client_id, allowing redirects etc to be validated, and the client_secret can be validated with only the client_id and the per_host_key. A nonce injected into the client_id JWT should ensure nobody can submit the same client metadata and retrieve the same client_secret

summary: JSXC demo
---

Try out JSXC easily by serving it from Prosodys built-in HTTP server.

Uses [mod_http_libjs] to serve jQuery, on Debian you can `apt install
libjs-jquery`.

# Configuration

mod_jsxc can be set up to either use resources from a separate HTTP
server or serve resources from Prosody's built-in HTTP server.

## Using CDN

`jsxc_cdn`
:   String. Base URL where JSXC resources are served from. Defaults to
    empty string.

`jsxc_version`
:   String. Concatenated with the CDN URL. Defaults to empty string.

## Local resources

Download a JSXC release archive and unpack it somewhere on your server.

`jsxc_resources`
:   String. Path to the `dist` directory containing JSXC resources on
the local file system. Disabled by default.

## Other options

`jquery_url`
:   String. URL or relative path to jQuery. Defaults to
    `"/share/jquery/jquery.min.js"` which will work with
    [mod_http_libjs].
