We’re trying to save bandwidth here, so we added to httpd.conf:
LoadModule deflate_module lib64/httpd/modules/mod_deflate. so
SetOutputFilter DEFLATE
DeflateCompressionLevel 9
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4.0[678] no-gzip
BrowserMatch bMSIE !no-gzip !gzip-only-text/html
DeflateFilterNote Input input_info
DeflateFilterNote Output output_info
DeflateFilterNote Ratio ratio_info
LogFormat ‘”%r” %b (%{input_info}n===>%{output_info}n) (%{ratio_info}n%%)’ deflate
CustomLog /var/log/httpd/deflate_log deflate
We can see some entries in the /var/log/httpd/deflate_log
