Here are the full explanations: - -- =gzip= -- Enables or disables gzipping of responses. -- =gzip_vary= -- Enables or disables inserting the "Vary: - Accept-Encoding" response header field if the directives gzip, - gzip_static, or gunzip are active. -- =gzip_min_length= -- Sets the minimum length of a response that will - be gzipped. The length is determined only from the "Content-Length" - response header field. -- =gzip_proxied= -- Enables or disables gzipping of responses for - proxied requests depending on the request and response. The fact that - the request is proxied is determined by the presence of the "Via" - request header field. -- =gzip_types= -- 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. -- =gzip_disable= -- Disables gzipping of responses for requests with - "User-Agent" header fields matching any of the specified regular - expressions. - - The special mask "msie6" (0.7.12) corresponds to the regular - expression "MSIE [4-6].", but works faster. Starting from version - 0.8.11, "MSIE 6.0; ... SV1" is excluded from this mask. - -More information on these directives and their options can be found on -the [[https://nginx.org/en/docs/http/ngx_http_gzip_module.html][Module -ngx_http_gzip_module]] page in Nginx's documentation. |
