This is for Pega version 8.5.2.

Our requirement is to configure a proxy server when doing a particular REST call. 

We were able to configure a proxy server at the JVM level by setting the Java arguments. However, that applies to all REST calls made in the same server. This breaks other REST calls that does not require the proxy.

This enhancement request is for an OOTB way to configure a proxy for a specific REST call. Few parameters we have in mind: ProxyHost ProxyPort ProxyUsername ProxyPassword

We have raised an SR (INC-168544) and was told this requirement is not supported and to proceed and raise this enhancement request.
