SharePoint and SAML Single Log Out

We did go down the road of modifying the logout.inc file for the policy. We did not do a function(0nL0ad) because we needed all the code on the logout.inc to run which takes care of all the session clean up etc. We simply added one line of code at the bottom of the logout.inc file just before the tag of:

window.location = " logout landing page";

The irule applied to the VIP then simply was this:

when HTTP_REQUEST { if { [string tolower [HTTP::uri]] contains "/_layouts/signout.aspx" || [string tolower [HTTP::uri]] contains "/_layouts/15/signout.aspx" || [string tolower [HTTP::uri]] contains "/_layouts/15/mobile/authn_signout.aspx"} { HTTP::respond 302 Location "/my.logout.php3" } }

Problem solved. :-)
