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).

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 — "". | |
