Specifying Hosts That Should Not Be Proxied
If your portal implementation retrieves content from both an intranet and the internet, you may have a problem retrieving both internal and external content if the proxy server is not aware of the address of the intranet content. You can prevent this situation by specifying that certain hosts (such as your intranet hosts) should not be accessed through the proxy server.
For Oracle WebLogic, specify the hosts not to be proxied in the HTTP_PROXY_NONPROXY_HTTPHOSTS and HTTP_PROXY_NONPROXY_HTTPSHOSTS environment variables with the setEnv.cmd (setEnv.sh in Unix) script. Refer to comments in setEnv for specific syntax.
You can list a set of patterns that should not be accessed through proxies, with each one separated by the pipe character ( | ). This example shows a setting that makes all HTTP connections to the eng domain bypass the proxy settings:
*.eng|*.eng.example.com
