SA-27069
Summary

Redirection appears to be in a loop, terminating request:
The issue persists after setting DSS "HTTP/SetSecureCookie" = false
Without Webseal it works fine. But with webseal enabled, it fails.
Error Messages
Redirection appears to be in a loop, terminating request
Steps to Reproduce
- Set up SSO through Composite Gateway.
- Login and try to access a page.
Root Cause
This issue seems to be a defect in Pega. The user also planning to use the the Gateway as proxy to multiple Pega server.
However the recommended way is to use webseal junction for each Pega server.
As Pega's recommendation going forward is not to use Gateway instead directly access IAC (Internet Application Composer) servlet, user was suggested for upgrade.
Resolution
Perform the following local-change steps:
1. Upgrade to Pega platform 7.1.2 and remove the Gateway.
2. Generate the new gadget code and set the following gadget parameters to resolve the issue:
- data-pega-gadgetname =''
- data-pega-action =''
- data-pega-action-param-query =''
- data-pega-isdeferloaded =''
- data-pega-applicationname =''
- data-pega-threadname =''
- data-pega-systemid =''
- data-pega-resizetype =''
- data-pega-url ='http://<server name>/prweb/IAC'>
