Root Cause

A defect in Pegasystems’ code or rules. Newer versions of the Weblogic server does not allow Carriage Return Line Feed (CRLF) characters in the URLs (also on the URL encoded form). The URL Encryption uses the Pega supplied Base64 encoding to encode the Cipher text. The Pega supplied Base64 Utils appends a newline character after every 72 characters. Network tools like Site-minder have policies which prevent having newline characters (both literal as well as encoded) in the URLs.


Apply HFix-59678.
