It works if you go through login.do > login_with_sso.do
but it doesn't work if you refresh with a specific page after logged out e.g (/now/nav/ui/home) and idP login prompt. It will return the the specific page instead of (/esc)
the changes i made as suggested from what i see online:
glide.entry.first.page.script = SPEntryPage().getFirstPageURL()
set session property starting_page to esc and nav_to to esc
getFirstPageURL: function() {
var session = gs.getSession();
this.logProperties('before', session);
// has roles and is not a Service Portal page - go to UI16
session.putProperty("starting_page", "/esc");
session.putProperty("nav_to", "/esc");
commented out as all users regardless of roles should be redirected
// if (user.hasRoles() && !redirectURL && !isServicePortalURL)
// return;
