mod_conversejs: Serve base app at / This makes things slightly less awkward for the browser to figure out which URLs belong to a PWA. The app's "start URL" was previously without the '/' and therefore was not considered within the scope of the PWA. Now the canonical app URL will always have a '/'. Prosody/mod_http should take care of redirecting existing links without the trailing / to the new URL. If you have an installation at https://prosody/conversejs then it is now at https://prosody/conversejs/ (the first URL will now redirect to the second URL if you use it). The alternative would be to make the PWA scope include the parent, i.e. the whole of https://prosody/ in this case. This might get messy if other PWAs are provided by the same site or Prosody installation, however.

This module implements a mechanism described in [XEP-0484: Fast Authentication Streamlining Tokens] via which clients can exchange a
password for a secure token, improving security and streamlining future reconnections.

This module depends on [mod_sasl2].

## Configuration

| Name                      | Description                                            | Default               |
|---------------------------|--------------------------------------------------------|-----------------------|
| sasl2_fast_token_ttl      | Default token expiry (seconds)                         | 86400*21 (21 days)  |
| sasl2_fast_token_min_ttl  | Time before tokens are eligible for rotation (seconds) | 86400 (1 day)       |

The `sasl2_fast_token_ttl` option determines the length of time a client can
remain disconnected before being "logged out" and needing to authenticate with
a password. Clients must perform at least one FAST authentication within this
period to remain active.

The `sasl2_fast_token_min_ttl` option defines how long before a token will be
rotated by the server. By default a token is rotated if it is older than 24
hours. This value should be less than `sasl2_fast_token_ttl` to prevent
clients being logged out unexpectedly.
