/**
 * Class for testing if ServerSignature works
 *
 * Testing the ServerSignature directive is of interest because the directive is a core feature.
 * If a core feature doesn't work, well, it it would seem that .htaccess files are disabled completely.
 * The test is thus special. If it returns *failure* it is highly probable that the .htaccess file has
 * not been read.
 *
 * Unfortunately, the test requires PHP to examine if a server variable has been set. So the test is not
 * unlikely to come out inconclusive due to a 403 Forbidden.
 *
 * Note that the test assumes that the ServerSignature directive has not been disallowed even though
 * it is technically possible to do so by setting *AllowOverride* to *None* and by setting *AllowOverrideList*
 * to a list that does not include *ServerSignature*.
