I need to enable gzip compression on oracle 11g and tried with this Want to enable GZip compression in Weblogic but in oracle 11g don't appear that menu item, somebody know where is the option in weblogic 11g I search in the console but I can't found it, or is there other way to resolve it?.
This configuration came just for 12c, you won't find it anywhere in 11g.
AFAIK, the most common way to accomplish compression in 11g is deploying a servlet filter. Please check this project: https://sourceforge.net/projects/pjl-comp-filter/
Hope it works for you.
