pyInvokeRESTConnector ignores proxy settings



User wants to use proxy (configured as command line parameters to JVM) to access REST Service using HTTPS. 

Step 11 of pyInvokeRESTConnector has sort of support for proxy settings, but step 12 where the actual connection is made ignores these settings. 

User also tried to use the code for BUG-140473, but the code itself only works for HTTP proxy settings per code review.

2. Observe using TCPmon (or any other traffic monitoring tool) that PRPC still will try to use direct connection and will fail at step 12. 

Root Cause

A defect in Pegasystems’ code or rules as pyInvokeRESTConnector ignores proxy settings.
