To disable mod_deflate in PHP (if needed), you can tell Apache with this :
apache_setenv('no-gzip', '1');If you set a variable, either new or existing, the corresponding $_SERVER variable is not changed, and you will have to change it as well.When you want to set variables to pass to Server Side Includes (.shtml) included in PHP scripts, use this.When you need to set the QUERY_STRING variable into a page included with the "virtual" function do this:
virtual ("some_page.shtml?$QUERY_STRING");
apache_setenv does not work for this case.
