Currently the application that is passing the X-Accel-Redirect uri back to nginx must set the Content-type header otherwise it will automatically be set to the default\_type setting. Is there a way to get nginx to automatically detect the mime settings and transmit it? I’ve tried: fastcgi\_ignore\_headers Content-Type, but that gave me the error (taken from [nginx, x-accel-redirect and mime types - Server Fault](http://serverfault.com/questions/195060/nginx-x-accel-redirect-and-mime-types)): [warn] 3988#1288: invalid value “Content-Type” Note: I’m using the latest windows build to test on.

This is not true. If not explicitly set by script together with X-Accel-Redirect - Content-Type will be set by nginx according to extension of redirect destination (and types/default\_type defined, see [1]).

See above for extension-based detection - this is how it works by default. Just not returning Content-Type with X-Accel-Redirect is enough. If you are talking about content sniffing - no, it’s not available (at all). > I’ve > tried: fastcgi\_ignore\_headers Content-Type, but that gave me the error > (taken from > [http://serverfault.com/questions/195060/nginx-x-accel-redirect-and-mime-types](http://serverfault.com/questions/195060/nginx-x-accel-redirect-and-mime-types)): > > [warn] 3988#1288: invalid value “Content-Type” Directive fastcgi\_ignore\_headers never accepted “Content-Type” value.

Thank you for your reply. You are correct – text/html was being sent prior to the response. I should have seen that. Much appreciated.
