Requests are not sent to nonProxyHosts system despite setting it



When setting the JVM settings to support proxy, Pega sends requests to a proxy despite configuring the host in the nonProxyHosts system property.

Error Messages

Not Applicable.

Steps to Reproduce

Set the following System properties to support proxy and non-proxy requests:
  • Dhttp.proxySet=true
  • Dhttp.proxyServer=[ipaddress]
  • Dhttp.proxyPort=[portnumber]
  • Dhttps.proxySet=true
  • Dhttps.proxyServer=[ipaddress]
  • Dhttps.proxyPort=[portnumber]
  • Dhttp.nonProxyHosts="[string of host names and ip addresses delimited by pipe]"

The traffic is redirected to a proxy server after the settings and system restart. However, all requests go to the proxy server.

Root Cause

A third-party product issue: Limitation with IBM Websphere.


Here's the explanation of the reported behavior:

The use of host names in http.nonProxyHosts or https.nonProxyHosts would not work because the target IP (IBM Websphere) address was used to determine non-proxy hosts.
