addParameter

public void addParameter(java.lang.String name,
                         java.lang.String value)

This methods adds parameters to the current request.

Parameters added here will be treated like parameters from the HttpRequest on included pages.

If a parameter exists, another value will be added to the array of values. If the value already exists for the parameter, nothing will be added, since a value can appear only once per parameter.

name - the name to add
