THttpClient->Flush() issue (connection thru proxy)

1) Issue with timeout at the moment of call THttpClient->Flush() when I try to get data thru proxy.
Prerequestites: clent(c# thrift) before proxy, we resource (in my case http://google.com)
Code:

 
class Program {
   static void Main(string[] args) {
	Uri uri = new Uri("http://google.com");
	TTransport transport = new THttpClient(uri);
  	transport.Flush();
   }
}

At the moment of call the method transport.Flush(); just goes to sleep forever (in my app).
Issue is locates in the: file Transport/THttpClient.cs -> method CreateRequest()
code:

 
connection.Proxy = null;

The lib should set state of proxy using some methods like to:
use default proxy - property WebRequest.DefaultWebProxy from namespace System.Net
add new property or methods with Proxy object
probably use a method of declaring an attribute in C# - to write own custom attribute(s) for class THttpClient; it's be able manage state of object inside without usage of some xml config files

2) Timeout period is not set by default.
Actually timeout period set to 0
Code (file Transport/THttpClient.cs):

private int connectTimeout = 0;
private int readTimeout = 0;

Need to set value of timeout by default like 15 seconds instead of infinite interval.

3) HttpWebRequest connection properties sets by default
Code (file Transport/THttpClient.cs -> method CreateRequest()):

connection.ContentType = "application/x-thrift";
connection.Accept = "application/x-thrift";
connection.UserAgent = "C#/THttpClient";
connection.Method = "POST";
connection.ProtocolVersion = HttpVersion.Version10;

But need to have a way to configure it options thru object or class attributes in client code
