/*
 * Unit test for 4925406 ("Add support for form-hint-field to determine
 * request encoding").
 *
 * In its sun-web.xml, the web module specifies a parameter-encoding element
 * with a form-hint-field attribute with value 'requestCharset'.
 *
 * Client appends to the request URI a query parameter named after the
 * form-hint-field. Query parameter specifies as its value the name of the
 * request charset, and would usually represent a hidden form field.
 *
 * Container is supposed to set the request encoding to the value of the query
 * parameter.
 *
 * JSP that is the target of the request retrieves the request encoding and
 * assigns it as the response encoding, which is checked by this client.
