Configuring HTTP Request Load Balancing

The Configure HTTP Request Load Balancing page is used to distribute the load among the specified origin server.

ProcedureTo Configure HTTP Request Load Balancing

  1. Access the Server Manager and click the Routing tab.

  2. Click the Configure HTTP Request Load Balancing link.

    The Configure HTTP Request Load Balancing page is displayed.

  3. Select the resource from the drop-down list or click the Regular Expression button, type a regular expression and click OK.

  4. Specify the URL of an origin server in the Server field. If multiple server parameters are given, the Proxy Server will distribute the load among the specified origin server.

  5. In the Sticky Cookie field, specify the name of the cookie that when present in a response will cause subsequent requests to stick to that origin server. The default value is JSESSIONID.

  6. In the Sticky Parameter field, specify the name of a URI parameter to inspect for route information. When the URI parameter is present in a request URI and its value contains a colon, followed by a route ID, the request will “stick” to the origin server identified by that route ID. The default value is jsessionid.

  7. In the Route Header field, specify the name of the HTTP request header that is used to communicate route IDs to origin servers. The default value is proxy-jroute.

  8. In the Route Cookie field, specify the name of the cookie that is generated by the Proxy Server when it encounters a sticky cookie in a response.

    The default value is JROUTE.

  9. Set the Rewrite Host option to indicate whether the Host HTTP request header is rewritten to match the host specified by the server parameter.

  10. Set the Rewrite Location option to indicate whether Location HTTP response headers that match the server parameter should be rewritten.

  11. Set the Rewrite Content Location option to indicate whether Content-location HTTP response headers that match the server parameter should be rewritten.

  12. Indicate whether the headername HTTP response headers that match the server parameter should be rewritten, where headername is a user-defined header name. Specify the headername in the Headername field.

  13. Click OK.

  14. Click Restart Required.

    The Apply Changes page is displayed.

  15. Click the Restart Proxy Server button to apply the changes.
