Basically I'm trying to show the UIProgressView to show the data being fetched from the web service. Now problem is that I'm getting the expectedContentLength for almost all the service that I call from my application and the response headers contains the Content-Length. But for one of the web service's response it doesn't return the expectedContentLength, instead always returns -1.
Following are the response headers that I get for two different web service response :
- Response header for which I get the content length.(Data from service is not huge)
{
Connection = "Keep-Alive";
"Content-Length" = 2689;
"Content-Type" = "application/json";
Date = "Tue, 23 Jun 2015 08:19:04 GMT";
"Keep-Alive" = "timeout=5, max=98";
Server = "Apache/2.4.10 (Win32) OpenSSL/1.0.1i PHP/5.5.15";
"X-Powered-By" = "PHP/5.5.15";
}
- Response header for which I don't get the content length. (Response contains the huge data, no files to be downloaded just JSON data)
{
Connection = "Keep-Alive";
"Content-Type" = "application/json";
Date = "Tue, 23 Jun 2015 08:12:34 GMT";
"Keep-Alive" = "timeout=5, max=97";
Server = "Apache/2.4.10 (Win32) OpenSSL/1.0.1i PHP/5.5.15";
"Transfer-Encoding" = Identity;
"X-Powered-By" = "PHP/5.5.15";
}
The Above service response contains huge data. When tested the response on Advanced rest client chrome's extension It gives following response header with "Transfer-Encoding" = chunked;.

Server: Apache/2.4.10 (Win32) OpenSSL/1.0.1i PHP/5.5.15
X-Powered-By: PHP/5.5.15
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: application/json
I used following links, but none of them helped me: Link1 , Link2 , Link3
Please help me. Thanks!
Updated code: After setting the Content-Lenth header on server side I got the valid response with Content-Length header on Advanced rest client chrome's extension.
Date: Wed, 24 Jun 2015 05:25:48 GMT
Server: Apache/2.4.10 (Win32) OpenSSL/1.0.1i PHP/5.5.15
X-Powered-By: PHP/5.5.15
Content-Length: 1272347
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: application/json
But on client side (i.e in iOS Application) I still didn't get the Content-Lenth header so that I can get the expectedContentLength value. I still get "Transfer-Encoding" = Identity; in the response header on my side. I have also set the Accept-Encoding header in the request as follows :
[req setValue:@"identity;q=0" forHTTPHeaderField:@"Accept-Encoding"];
Is there anything more to be done on either side(server/client).
