split_clients

Syntax:	`split_clients string $variable { ... }`
Default:	—
Context:	`http`

Creates a variable for A/B testing, for example:

split_clients "${remote_addr}AAA" $variant {
               0.5%               .one;
               2.0%               .two;
               *                  "";
}

The value of the original string is hashed using MurmurHash2. In the example given, hash values from 0 to 21474835 (0.5%) correspond to the value ".one" of the $variant variable, hash values from 21474836 to 107374180 (2%) correspond to the value ".two", and hash values from 107374181 to 4294967295 correspond to the value "" (an empty string).
