Entry Point / LoginHook for Windchill PDMLink M10

Hello Experts,

In reading other posts and as a workaround to a problem implementing a SAML project, we are investigating the implementation of a loginHook, override to the SessionUserAuditEvent.LOGIN event by implementing a custom handler to URL encode the '#' character prior to a 302 redirection to the SP &  to maintain the state of a request and ensure a user goes to the requested page instead of the windchill default page.

Is anyone able to advise or comment if this would be the right entry point ?
