Hope everyone is doing well.
Let describe my situation to you :-
I have EBS R12.2.4 and as most of you know there is OHS already installed with This version , The EBS will be configured as SSO Using OAM, OID, and OIM and the customer wants to install and configure another OHS on different server that will redirect the transaction to EBS R12.2.4 regarding to my knowledge OHS can't redirect to another OHS am i right ? and if this applicable how can i do this ? what is the necessary steps to do it ?
OHS can redirect. It is just apache so any of the apache mod_rewrite directives will work in OHS also.
