comparison xml/ru/docs/http/ngx_http_split_clients_module.xml @ 76:4a4caa566120

Russian documentation import. Changes in module.dtd: <example> now allowed to contain <value> and <emphasis> elements (we need this to show important parts in examples), less strict checking of <directive> syntax (we don't want to fully document some directives, notably deprecated ones). Known issues: 1. <syntax> elements are preserved as is, they will require manual conversion (likely to some not-yet-existed format a la DocBook cmdsynopsis, as currently used one seems to be incomplete); 2. <value> no longer corresponds to replaceable content, and it's use in examples isn't correct; 3. <link doc="document#fragment"> doesn't work with current xslt, either should be supported or changed to <link doc="document" id="fragment">. The following files are intentionally omitted: maillists.xml (support.xml should be used instead), experimental.xml (obsolete), faq.xml (conflicts with existing one, needs discussion). Not yet linked to site.

46 Директива создаёт переменную для A/B split-тестирования, например:
47 <example>
48 split_clients "${remote_addr}AAA" $variant {
49 0.5% .one;
50 2.0% .two;
51 * "";
52 }
53 </example>
54 Значение исходной строки переменных хэшируется с помощью CRC32.
55 В приведённом примере при значениях хэша от 0 до 21474836 (0.5%)
56 переменная $variant получит значение ".one".
57 При значениях хэша от 21474837 до 107374182 (2%) — ".two".
58 И при значениях хэша от 107374183 до 4294967297 — "".
