#开启GzipgzipOn ;    #不压缩临界值, more than 10K compression, generally do not change gzip_min_length 10k; #设置gzip申请内存的大小, the function is to request memory space in multiples of block size gzip_buffers448k; #用了反向代理的话, end communication is HTTP/1.0, there should be no need to look at me this popular science, there are words to comment on the line, the default is http/1.1gzip_http_version1.0; #压缩级别,1-9, the greater the number of compression of the better, the longer the time, look at the mood casually change it gzip_comp_level6; #设置需要压缩的MIME类型, non-set values are not compressed gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/PNG; #跟Squid等缓存服务有关, on will increase in the header."vary:accept-encoding"gzip_vary off; #IE6对Gzip不怎么友好, don't give it a gzip gzip_disable"MSIE [1-6]\.";
