custom code on your Synapse homeserver. Server admins are encouraged to verify the
provenance of the modules they use on their homeserver and make sure the modules aren't
running malicious code on their instance.
## Using multiple modules
Also note that we are currently in the process of migrating module interfaces to this
system. While some interfaces might be compatible with it, others still require
configuring modules in another part of Synapse's configuration file.
The order in which modules are listed in this section is important. When processing an
action that can be handled by several modules, Synapse will always prioritise the module
that appears first (i.e. is the highest in the list). This means:
* If several modules register the same callback, the callback registered by the module
that appears first is used.
* If several modules try to register a handler for the same HTTP path, only the handler
registered by the module that appears first is used. Handlers registered by the other
module(s) are ignored and Synapse will log a warning message about them.
Note that Synapse doesn't allow multiple modules implementing authentication checkers via
the password auth provider feature for the same login type with different fields. If this
happens, Synapse will refuse to start.
## Current status
We are currently in the process of migrating module interfaces to this system. While some
interfaces might be compatible with it, others still require configuring modules in
another part of Synapse's configuration file.
Currently, only the following pre-existing interfaces are compatible with this new system:
* spam checker
* third-party rules
* presence router
* password auth providers

## Requirement for X-Forwarded-Proto header

#
# Each job's configuration defines which range of message lifetimes the job
# takes care of. For example, if 'shortest_max_lifetime' is '2d' and
# 'longest_max_lifetime' is '3d', the job will handle purging expired events in
# rooms whose state defines a 'max_lifetime' that's both higher than 2 days, and

#
# The rationale for this per-job configuration is that some rooms might have a
# retention policy with a low 'max_lifetime', where history needs to be purged
# of outdated messages on a more frequent basis than for the rest of the rooms
# (e.g. every 12h), but not want that purge to be performed by a job that's
# iterating over every room it knows, which could be heavy on the server.
#
# If any purge job is configured, it is strongly recommended to have at least
# a single job with neither 'shortest_max_lifetime' nor 'longest_max_lifetime'
# set, or one job without 'shortest_max_lifetime' and one job without
# 'longest_max_lifetime' set. Otherwise some rooms might be ignored, even if
