Below is generic detail regarding RedirectGuests type, hope this helps
RedirectGuests Type: boolean
Functionality: Process Commander sends information between the server and the client (browser) using URLs. These URLs can contain “query strings” which display calls to activities in the system or output streams of data.
PegaRULES typically redirectes guests to the standard URL format above in preparation for interactive authentication. Not all authentication schemes require this; if your authentication scheme doesn’t require interaction, set this entry to false to reduce network traffic.
NOTE: If the initialization setting NodeType is set to “web”, the default of the RedirectGuests setting changes to false.
