Hi, Taken from the example were the Accept-Language (and it qualifiers) HTTP header is overridden by a cookie set in the user’s browser; from http://httpd.apache.org/docs/2.2/content-negotiation.html#better : SetEnvIf Cookie "lang=(.+)" prefer-language=$1 Header append Vary cookie But can this be done with the Accept HTTP header as well? Is there an environmental variable that can be used to override the default negotiation method for the Content-Type as well? I had visioned something like the below, but I have not found anything in the documentation. SetEnvIf Cookie "type=(.+)" prefer-type=$1 Header append Vary cookie If this is an undocumented or unsupported feature… How can I achieve the same result using other approaches? Basically I want to offer the user a way to override the default content negotiation method. Like with the prefer-language option. -- Daniel’s linux notebook – http://www.opensource-notebook.com/ --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
