Syntax: ssi_value_length length; Default: ssi_value_length 256; Context: http, server, location Sets the maximum length of parameter values in SSI commands.

Syntax: ssi_types mime-type ...; Default: ssi_types text/html; Context: http, server, location Enables processing of SSI commands in responses with the specified MIME types in addition to “text/html”. The special value “*” matches any MIME type (0.8.29).

Syntax: ssi_last_modified on | off; Default: ssi_last_modified off; Context: http, server, location This directive appeared in version 1.5.1.

Syntax: split_clients string $variable { ... } Default: — Context: stream Creates a variable for A/B testing, for example: split_clients "${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 v

Syntax: spdy_headers_comp level; Default: spdy_headers_comp 0; Context: http, server Sets the header compression level of a response in a range from 1 (fastest, less compression) to 9 (slowest, best compression). The special value 0 turns off the header compression.
