LibCurl Time out Issue

Hi there,

I am new to this forum. I am using libcurl to download files from the
server to the client. I am using the following options in my curl
connection in client side,

curl_easy_setopt(curlPtr, CURLOPT_LOW_SPEED_LIMIT, 1);
curl_easy_setopt(curlPtr, CURLOPT_LOW_SPEED_TIME, 360L);
curl_easy_setopt(curlPtr, CURLOPT_IGNORE_CONTENT_LENGTH, 1);
curl_easy_setopt(curlPtr, CURLOPT_TCP_NODELAY, 1);

Even though I have made it to time out only if no bytes was received for a
period of 6 minutes (360 seconds), the operation seems to be timed out even
after receiving response bytes within the stipulated time.

Here is my response in client side. I have edited ssl certificate details
for confidentiality.

* Connection #0 seems to be dead!* Closing connection #0* About to
connect() to port 34007 (#0)* Trying *
TCP_NODELAY set* connected* Connected to ( port

    * Operation timed out after 360000 milliseconds with 205512 bytes received
    * Closing connection #0

I am using the libcurl version 7.19.3. I know it is an older version. But
please let me know what is went wrong here. Does upgrading to latest
version help in my case. I would appreciate your answer.

P.S Kindly redirect the mailing group if I am mailed to wrong mailing list.
