Geoff-

in Directory for a user can set cacheable=true like this:

<user id='1000' cacheable='true'>
     <params>
         <param name='password' value='password123'/>
     </params>
     <variables>
      <variable name='toll_allow' value='domestic,international,local'/>
      <variable name='accountcode' value='1000'/>
      <variable name='user_context' value='defaukt'/>
      <variable name='effective_caller_id_name' value='Extension 1000'/>
      <variable name='effective_caller_id_number' value='1000'/>
      <variable name='outbound_caller_id_name'
value='$${outbound_caller_name}'/>
      <variable name='outbound_caller_id_number'
value='$${outbound_caller_id}'/>
     </variables>
    </user>

See this link:
https://freeswitch.org/confluence/display/FREESWITCH/mod_xml_curl#Caching_objects

And then the user is stored in memory so re-register authentication comes
from memory rather than another lookup.

If the user is deleted/disabled or changes password then the cache should
be cleared for that user. Like this:  xml_flush_cache id 1000 domainname

See below for reference:

If you then make a change to the directory you should run the
xml_flush_cache command to clear, some examples:

# This clears items for user 1001
xml_flush_cache id 1002 domain-name

# This clears all items
xml_flush_cache

You may also wish to enable an expiry on the cache entries by setting the
cacheable attribute to a numeric value which would be the number of
milliseconds, see http://jira.freeswitch.org/browse/FS-4871

      <user id="1002" cacheable="60000">

will cache the result for 60 seconds (60000 milliseconds)

*ALSO-*

Preloading in the config files also reduces requests:

In freeswitch.xml replace the section for dialplan with a pre-process wget
statement to load the dialplan:

*Something like this:*

<section name="dialplan" description="Regex/XML Dialplan">

 <X-PRE-PROCESS cmd="exec" data="wget --post-data
'SomePOSTVariable=SomePOSTValue' -q --output-document=-
https://someURLtheReturnsDialplan/api/ICSwitch/ICDialplan" />

     <!--  <##X-PRE-PROCESS cmd="include" data="dialplan/*.xml"/>  -->

  </section>

Hope this helps.

Thanks,

Tony
