-/**
- * This is a servlet that proxies request to another servlet.
- *
- * SERVLET REDIRECTION
- * Specify the URL of a servlet to forward the request to
- * destServlet: /ee/ca/newservlet
- *
- * PARAMETER MAPPING
- * In the servlet configuration (as an init-param in web.xml) you
- * can optionally specify a value for the parameter 'parameterMap'
- * which contains a list of HTTP parameters which should be
- * translated to new names.
- *
- * parameterMap: name1->newname1,name2->newname2
- *
- * Optionally, names can be set to static values:
- *
- * parameterMap: name1->name2=value
- *
- * Examples:
- * Consider the following HTTP input parameters:
- * vehicle:car make:ford model:explorer
- *
- * The following config strings will have this effect:
- * parameterMap: make->manufacturer,model->name=expedition,->suv=true
- * output: vehicle:car manufactuer:ford model:expedition suv:true
- *
- * @version $Revision$, $Date$
