attach Enterprise portal only to the only1 application instance on HP-UX

Hello

I have mixed environment 1 DBCntral Instance 1 application instance on HP-UX/Oracle.In addition I have 2 virtual linux application servers for performance reason.

I would like to attach an Enterprise portal only to the 1 application instance on HP-UX/Oracle via HTTPS. Is it possible? Namely i do have cryptoli librries only for PA-RISSC andalso I would not lke to put Enterprise Portal load on all servers.

Is there any problem by doing so. ANyway EP will communicaet to backend system via logon group where only application instance on HP-UX/Oracle will be present. (I guess on othr servers I do not need HTTPS)

Thank you in advance
