Nginx compress mime types with parameters

I have Nginx reverse proxying my service that works by OData protocol. I'm trying to enable compression for theese requests by putting 

#...
gzip on;
gzip_types application/json;
#...
server {
   #...
   location /odata/ {
      proxy_pass http://localhost:7700/odata/;
   }
   #...
}

in nginx.conf.

Sometimes my service returns

Content-Type: application/json; charset=utf-8; odata.metadata=minimal

and Nginx compresses it.

But sometimes my service returns

Content-Type: application/json; odata.metadata=minimal; odata.streaming=true; charset=utf-8

and Nginx doesn't compress such responses.

What should I do to enable Nginx compressing such responses?

Solution

  • Solved this problem by writing middleware in my application, that changes Content-Type header and transforms it to application/json; charset=utf-8; odata.metadata=minimal; odata.streaming=true;

    After that Nginx could recognize it as json content type and compresses it.
