android - Volley response headers

I try to use volley for http request. I tried a request on postman and the response headers are below :

  1. Content-Encoding →gzip
  2. Content-Length →153
  3. Content-Type →application/json; charset=utf-8
  4. Date →Fri, 30 Jun 2017 13:36:10 GMT
  5. ETag →W/"23-E742p6pP4kakmVh3lok1ww"
  6. Server →Microsoft-IIS/8.0
  7. Vary→X-HTTP-Method-Override, Accept-Encoding,Accept-Encoding
  8. X-Powered-By →Express, ASP.NET

Volley adds some extra keys and removes Content-Length and Content-Encoding key. I write keys and values on parseNetworkResponse function. Response headers are below :

Content-Type : application/json; charset=utf-8 Date : Fri, 30 Jun 2017 09:05:23 GMT ETag : W/"23-E742p6pP4kakmVh3lok1ww" Server : Microsoft-IIS/8.0 Set-Cookie : ARRAffinity=16d81073e15abb17d2faba962adb6504734210ff2b9ff1ddfa770750ac7752e2;Path=/;xxx.net Vary : X-HTTP-Method-Override, Accept-Encoding,Accept-Encoding X-Android-Received-Millis : 1498813523832 X-Android-Response-Source : NETWORK 200 X-Android-Selected-Protocol : http/1.1 X-Android-Sent-Millis : 1498813523632 X-Powered-By : Express

Why does it change content? How can I get Content-Length and Content-Encoding?

if you are using the java.net.HttpURLConnection and the getHeaderFieldKey method, then do not forget to check the 0th element from the header according to the API reference:

Some implementations may treat the 0th header field as special, i.e. as the status line returned by the HTTP server. In this case, getHeaderField(0) returns the status line, but getHeaderFieldKey(0) returns null.
