Configure the Proxy Plug-In for the Web Server

You install the proxy plug-in so that WebSphere can communicate with the web server.

Follow these steps:

See the WebSphere Management and Administration Redbook for instructions about installing the proxy plug-in for the web server. The chapter on Session Management discusses this plug-in.
Restart the Web server to activate the plug-in.
- For IIS Web Servers—In the master WWW service, be sure that the WebSphere plug-in (sePlugin) appears after the SiteMinder Web Agent plug-in and that the WebSphere plug-in started successfully.
- For Sun Java System Web Servers—Be sure that the WebSphere plug-in (libns41_http.so) is loaded after the SiteMinder Web Agent plug-in (NSAPIWebAgent.so)
  For Sun Java System 6.0 Web Servers, check the order of plug-ins in <sun_java_home>/https-instance/config/magnus.conf.
  
  For Sun Java System 5.x Web Servers, copy the following lines from <iplanet_home>/https-instance/config/magnus.conf to <iplanet_home>/https-instance/config/obj.conf
```
Init fn="load-modules" funcs="as_init,as_handler,as_term" shlib="/export/WebSphere/AppServer/bin/libns41_http.so"
Init fn="as_init" bootstrap.properties="/export/WebSphere/AppServer/config/cells/plugin-cfg.xml"
```
  Add the following after AuthTrans fn="SiteMinderAgent" in the obj.conf file:
```
Service fn="as_handler"
```
- For Apache Web Servers— In the Dynamic Shared Object (DSO) Support section of Apache_home/config/httpd.conf, be sure that the SiteMinder Web Agent plug-in (mod2_sm.so)is loaded before the WebSphere plug-in (mod_ibm_app_server_http.so).
