replace path dynamically in httptargetconnection based on condition of requesturi in apigeex

Hi @dchiesa1 @kurtkanaskie We have a requirement where there are two different URI paths to the target & which calling target server from apigeex Is there a way to replace path dynamically in the HTTPTargetconnection? Is there a policy that could check the incoming request.uri & set the path to the HTTPTargetconnection dynamically?

Hi @raghunathapalle 

Yes, that is a common scenario. You have options.

Option 1 - set `target.url` directly in the target flow. Then it doesn't matter what's in the `URL` of the HTTPTargetConnection.

<AssignMessage name="AM-Target-URL">
    <!-- Put in target pre flow -->
    <AssignVariable>
        <Name>target.url</Name>
        <Ref>target_scheme_host_basepath_and_suffix</Ref>
    </AssignVariable>
</AssignMessage>

Option 2 - set the `URL` path suffix using a flow variable

<AssignMessage name="AM-Target-Params">
    <AssignVariable>
        <Name>target.copy.pathsuffix</Name>
        <Value>false</Value>
    </AssignVariable>
    <AssignVariable>
        <Name>target.copy.params</Name>
        <Value>false</Value>
    </AssignVariable>
    <AssignVariable>
        <Name>new_target_pathsuffix</Name>
        <Value>echo/hello/apigeek</Value>
    </AssignVariable>
</AssignMessage>

Set the `URL` using flow variable.

    <HTTPTargetConnection>
        <!-- Neither of these work, need to use AM-Target-URL, last 2 works in Service Callout tho -->
        <!--
        <URL>https://{flow.target.host_basepath_and_suffix}</URL>
        <URL>https://{flow.target.host}/{flow.target.basepath_and_suffix}</URL>
        <URL>https://{flow.target.host}/{flow.target.basepath}/{flow.target.suffix}</URL>
        -->
        <!-- This doesnt work, needs protocol -->
        <!--
        <URL>{flow.target.scheme_host_basepath_and_suffix}</URL>
        -->
        <!-- This works -->
        <URL>https://mocktarget.apigee.net/{new_target_pathsuffix}</URL>      
    </HTTPTargetConnection>

Hope that helps!
