I am uses NSURLConnection to download files.(Basically I use JGDownload Accelerator)
My issue is when I try to download files at one particular server, response provided by server is vary and gives me different header responses like below
Printing description of headers:
{
"Accept-Ranges" = bytes;
"Cache-Control" = "max-age=687749";
Connection = "keep-alive";
"Content-Length" = 35617808;
"Content-Type" = "video/mp4";
Date = "Fri, 11 Sep 2015 07:21:59 GMT";
Etag = "\"ee90ce32a16fc115d0799d686e5fe1b4\"";
Expires = "Sat, 19 Sep 2015 06:24:28 GMT";
"Keep-Alive" = "timeout=20";
"Last-Modified" = "Wed, 09 Sep 2015 13:41:37 GMT";
Server = ucdn;
"X-Timestamp" = "1441806096.99264";
"X-Ureq-ID" = "PYMqMNZBGw7LI3xeAHCTQwJs2FvO0y0xuG3+g5B0KcBzTv1v4kTfwCzHQYgrBEGSJQ0tBMG5L+srffrjBfio1R1ChR+wABEHY92PCg==";
"X-VHostId" = "10000, 200000";
}
{
"Cache-Control" = "max-age=687430";
Connection = "keep-alive";
"Content-Length" = 1;
"Content-Range" = "bytes 0-0/35617808";
"Content-Type" = "video/mp4";
Date = "Fri, 11 Sep 2015 07:27:18 GMT";
Etag = "\"ee90ce32a16fc115d0799d686e5fe1b4\"";
Expires = "Sat, 19 Sep 2015 06:24:28 GMT";
"Keep-Alive" = "timeout=20";
"Last-Modified" = "Wed, 09 Sep 2015 13:41:37 GMT";
Server = ucdn;
"X-Timestamp" = "1441806096.99264";
"X-Ureq-ID" = "PYMqMNZBGw7LI3xeAHCTQwJs2FvO0y0xuG3+g5B0KcBzTv1v4kTfwCzHQYgrBEGSJQ0tBMG5L+srffrjBfio1R1ChR+wABEHY92PCg==";
"X-VHostId" = "10000, 710000";
}
Basic deference is the content-length key as in first one it provide proper value and in second one it is wrong and where I got delay around 30 - 40 seconds.
Is there any way I can avoid that delay? Or any workaround to make response fast I means server provides data with in 1 to 2 seconds but the callback method provides data late
for the request / response time I use Charles application. Results I found by it is HERE
I have tried all the possible ways to reduce the time delay but it seems that there is no way available using NSURLConnection. So we have requested for the Apple Engineer Support for this issue and will get some response from them in while.
Till then there is no other way to avoid this delay due to wrong header information from server.
I will update here if I get any response from Apple.
