18 Chi, nel corso della propria esperienza con host condivisi, e' sempre
19 stato abituato a configurare <i>tutto</i> usando <i>solo</i> i file
20 .htaccess di Apache, in genere converte le seguenti regole:
21
22 <programlisting>
23 RewriteCond %{HTTP_HOST} example.org
24 RewriteRule (.*) http://www.example.org$1
25 </programlisting>
26
27 in qualcosa tipo:
28
29 <programlisting>
30 server {
31 listen 80;
32 server_name www.example.org example.org;
33 if ($http_host = example.org) {
34 rewrite (.*) http://www.example.org$1;
35 }
36 ...
37 }
38 </programlisting>

42 Si tratta di una soluzione errata, poco elegante e inefficiente.
43 La soluzione corretta prevede la definizione di un server distinto per
44 <literal>example.org</literal>:
45
46 <programlisting>
47 server {
48 listen 80;
49 server_name example.org;
50 return 301 http://www.example.org$request_uri;
51 }
52
53 server {
54 listen 80;
55 server_name www.example.org;
56 ...
57 }
58 </programlisting>
59
60 <note>
61 Nelle versioni antecedenti la 0.9.1, i redirect possono essere definiti con:
62 <programlisting>
63 rewrite ^ http://www.example.org$request_uri?;
64 </programlisting>
65 </note>

75 Un altro esempio:
76 invece della logica &ldquo;upside-down&rdquo;, vale a dire &ldquo;tutto quello
77 che non e' <literal>example.com</literal> ne' <literal>www.example.com</literal>&rdquo;:
78
79 <programlisting>
80 RewriteCond %{HTTP_HOST} !example.com
81 RewriteCond %{HTTP_HOST} !www.example.com
82 RewriteRule (.*) http://www.example.com$1
83 </programlisting>
84
85 e' meglio semplicemente definire
86 <literal>example.com</literal>, <literal>www.example.com</literal>,
87 e &ldquo;tutto il resto&rdquo;:
88
89 <programlisting>
90 server {
91 listen 80;
92 server_name example.com www.example.com;
93 ...
94 }
95
96 server {
97 listen 80 default_server;
98 server_name _;
99 return 301 http://example.com$request_uri;
100 }
101 </programlisting>
102
103 <note>
104 Nelle versioni antecedenti la 0.9.1, i redirect possono essere definiti con:
105 <programlisting>
106 rewrite ^ http://example.com$request_uri?;
