For WebCenter components that run on Oracle WebLogic Server, you can set Oracle HTTP Server (OHS) as the frontend to Oracle WebLogic Server. Some scenarios that require OHS as the frontend are:
For OSSO to function properly between Site Studio and Oracle Content Server UI. This is achieved through mod_osso of OHS.
The adequate distribution of load across the Oracle WebLogic Server cluster nodes. This is achieved through mod_wl of OHS.
OHS is also required for OAM's WebGate component.
OHS is used as a reverse proxy.
In these cases, you must configure the mod_wl_ohs module to allow requests to be proxied from an OHS to Oracle WebLogic Server. For information, see the section "Configure the mod_wl_ohs Module on Oracle HTTP Server" in Oracle Fusion Middleware Administrator's Guide for Oracle HTTP Server.
After you have configured the mod_wl_ohs module using the Fusion Middleware Control, the mod_wl_ohs.conf file looks similar to Example B-1. The default location of this file is: OHS_HOME/Oracle_WT1/instances/instance1/config/OHS/ohs1/mod_wl_ohs.conf.
Example B-1 WebCenter Spaces - Sample mod_wl_ohs.conf File

If you have configured SSL, then the following additional directives are required:
WLProxySSL ON
WLProxySSLPassThrough ON
For example, mod_wl_ohs.conf entries looks like Example B-2:
Example B-2 WebCenter Spaces - mod_wl_ohs.conf File with SSL Directives
# WebCenter Spaces <Location /webcenter> SetHandler weblogic-handler WeblogicHost webcenter.example.com WeblogicPort 8888 WLProxySSL ON WLProxySSLPassThrough ON </Location> <Location /webcenterhelp> SetHandler weblogic-handler WeblogicHost webcenter.example.com WeblogicPort 8888 WLProxySSL ON WLProxySSLPassThrough ON </Location> ...
Frontend Listening Host and Frontend Listening Port
If the Oracle HTTP Server (OHS) frontend is also the site entry point, use the Oracle WebLogic Server Administration Console to set the FrontEnd Host and FrontEnd HTTP Port for each server that uses the OHS frontend.
