mod_adhoc_dataforms_demo: Fix duplicate field prevention It's supposed to only include each type of form field once per form at most but it didn't note which fields it had added already. No idea what the probability was anyways, probably pretty low.

summary: Prevent communication between hosts
...

Introduction
============

In some environments it is desirable to isolate one or more hosts, and
prevent communication with external, or even other internal domains.

Loading mod\_isolate\_host on a host will prevent all communication with
JIDs outside of the current domain, though it is possible to configure
exceptions.

**Note:** if you just want to prevent communication with external
domains, this is possible without a plugin. See [Prosody: Disabling
s2s](http://prosody.im/doc/s2s#disabling) for more information.

This module was sponsored by [Exa Networks](http://exa-networks.co.uk/).

Configuration
=============

To isolate all hosts by default, add the module to your global
modules\_enabled:

``` {.lua}
modules_enabled = {
  ...
    "isolate_host";
  ...
}
```

Alternatively you can isolate a single host by putting a
modules\_enabled line under the VirtualHost directive:

``` {.lua}
VirtualHost "example.com"
modules_enabled = { "isolate_host" }
```

After enabling the module, you can add further options to add exceptions
for the isolation:

  Option                     Description
  -------------------------- -----------------------------------------------------------------------------------------
  isolate\_except\_domains   A list of domains to allow communication with.
  isolate\_except\_users     A list of user JIDs allowed to bypass the isolation and communicate with other domains.

**Note:** Admins of hosts are always allowed to communicate with other
domains
