Downloading Guest file through HTTP Get request on URL is timing out after 100seconds.

To download the guest file

a. Get url of the file by calling C# SDK InitiateFileTransferToGuest

as mentioned in https://www.vmware.com/support/developer/converter-sdk/conv50_apireference/vim.vm.guest.FileManager.html

b. Used C# SDK to get the file contents

  var request = (HttpWebRequest)HttpWebRequest.Create(url);

            request.Method = "GET";

            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())

            {

                Stream dataStream = response.GetResponseStream();

                StreamReader reader = new StreamReader(dataStream);

                fileContent = reader.ReadToEnd();

                reader.Close();

                dataStream.Close();

            }

Error

While calling Http Get on url 'https://10.20.64.173:443/guestFile?id=299&token=5254f16d-d5f6-6222-7645-0e1d32810eb2299', the request gets time out after 100 seconds for each and every VM.

Failed with System.Net.WebException exception and message The operation has timed out.

"StackTrace:   at System.Net.HttpWebRequest.GetResponse()

Workaround:

Although I can increase the timeout by setting timeout attribute to something more than default value of 100s.

Ask is

1. How to make my vcenter server respond within 100seconds.

2. It would be great if anyone could point me out to architecture, of how the file transfer work in vcenter, in o.w. does the file contents are copied to from guest to webserver which seems to be less scalable.
