Routing requests from a plug-in to a proxy server

This topic provides information on setting up a WebSphere Application Server plug-in to route requests to a proxy server.

Why and when to perform this task

An administrator may choose to set up a Web server, such as IBM HTTP Server, with the WebSphere Application Server plug-in as a front-end to the proxy server. The plug-in configuration file for such a topology cannot use the traditional plug-in configuration generation mechanism if the requests are routed through the proxy server.

To generate the plugin-cfg.xml file to use with the Web server plug-in to route through the proxy server, complete the following steps:

Steps for this task

  1. From the administrative console, click Servers > Proxy servers > <server name> > HTTP proxy server settings > Proxy settings.
  2. In the Proxy plug-in configuration policy section, click Enable policy.
  3. In the Generate plug-in configuration drop-down menu, select the cell scope. This generates the plugin-cfg.xml file for all proxy servers in the cell. You will find the plugin-cfg.xml in the <profile_dir>/etc/plugin-cfg.xml directory. Select node or server for a smaller scope.
  4. Enter the path to the script in the Plugin config change script field if you have a script that will manually copy the plugin-cfg.xml file from the node to the plug-in installation location.
  5. Click OK.
  6. Disable the automatic propagation of the plug-in if you are using IBM HTTP Server with remote administration. From the administrative console, click Servers > Web servers > server name> > Plug-in properties. Deselect Automatically propagate plugin configuration file. This will prevent WebSphere Application Server from copying the traditional plugin-cfg.xml file over the proxy server plugin-cfg.xml file.
  7. Save your changes.
  8. Stop and restart the proxy server. The plugin-cfg.xml file will be in the <install_root>/<profile_dir>/etc/plugin-cfg.xml directory for the node. If you do not have a script in the Plugin config change script field, manually copy the plugin-cfg.xml file to the plug-in.
