CDC Servlet inserts custom HTTP response header (6800246)

In patch 4, if you integrate Cross-Domain Single Sign-On (CDSSO) with programmatic clients, the CDC Servlet inserts an extra HTTP response header (which is not configurable). For example, with a web agent installed in CDSSO mode, viewing a response on “Live HTTP Headers”, you will see the Cdcservlet_auto_post: true header. This change allows custom applications to easily distinguish the auto submitting form and to process the information accordingly.
