# Compression
#
# The ngx_http_gzip_module module is a filter that compresses responses using
# the “gzip” method. This often helps to reduce the size of transmitted data by
# half or even more.

# Enables or disables gzipping of responses.
# Default: off;
gzip on;

# Sets the number and size of buffers used to compress a response. By default,
# the buffer size is equal to one memory page. This is either 4K or 8K,
# depending on a platform.
# Default 32bit (i386): 32 4k
# Default 64bit (x64): 16 8k;
#gzip_buffers 16 8k;

# Sets a gzip compression level of a response. Acceptable values are in the
# range from 1 to 9.
# Default: 1
gzip_comp_level 5;

# Disables gzipping of responses for requests with “User-Agent” header fields
# matching any of the specified regular expressions.
# Default: <not set>
#gzip_disable msie6;

# Sets the minimum length of a response that will be gzipped. The length is
# determined only from the “Content-Length” response header field.
# Default: 20
#gzip_min_length 256;

# Sets the minimum HTTP version of a request required to compress a response.
# Default: 1.1
#gzip_http_version 1.1;

# Enables or disables gzipping of responses for proxied requests depending on
# the request and response.
# Default: off;

# Enables gzipping of responses for the specified MIME types in addition to
# “text/html”. The special value “*” matches any MIME type (0.8.29). Responses
# with the “text/html” type are always compressed.
# Default: text/html
