Extract variable from LookupCache

[jcds101092]

Hello

How can I get the value of the variable that is inside the tag called <AssignTo> with policy ExtractVariables  ??

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

<LookupCache continueOnError="false" enabled="true" name="LC-testLookupCache">

<DisplayName>LC-testLookupCache</DisplayName>

<Properties/>

<CacheKey>

<Prefix/>

<KeyFragment>apivar</KeyFragment>

<KeyFragment ref="request.queryparam.myvar"/>

</CacheKey>

<CacheResource>my_cache</CacheResource>

<Scope>Exclusive</Scope>

<AssignTo>myvar</AssignTo>  -- I need the value of this variable called "myvar"

</LookupCache>

You would "get it" by referencing that variable in some other policy. For example, after the LookupCache, you could then use AssignMessage to inject that variable into a request header which will be sent to the upstream system. If your lookupCache assigns to the variable named variable_set_from_lookupcache, then the subsequent AssignMessage might be like this:

<AssignMessage name='AM-Inject-Header'> 
  <!-- 
   When this policy is attached to the request flow, it will
   inject a header into the request that will be sent to the 
   upstream system.
  -->
  <Set> 
    <Headers> 
      <Header name='new-header'>{variable_set_from_lookupcache}</Header>
    </Headers>
  </Set>
</AssignMessage>
