6	* Class for testing if ServerSignature works
7	*
8	* Testing the ServerSignature directive is of interest because the directive is a core feature.
9	* If a core feature doesn't work, well, it it would seem that .htaccess files are disabled completely.
10	* The test is thus special. If it returns failure it is highly probable that the .htaccess file has
11	* not been read.
12	*
13	* Unfortunately, the test requires PHP to examine if a server variable has been set. So the test is not
14	* unlikely to come out inconclusive due to a 403 Forbidden.
15	*
16	* Note that the test assumes that the ServerSignature directive has not been disallowed even though
17	* it is technically possible to do so by setting AllowOverride to None and by setting AllowOverrideList
18	* to a list that does not include ServerSignature.
19	*
