HTTP requests through SOCKS-Proxy getting redirected (HTTP 302) C#

Question

Hey guys I have written some code to connect to a SOCKS5-Proxy and handle some HTTP requests, the problem is that every request I'm doing keeps getting redirected (HTTP 302 Response).

My Request code:

try
{
    using (var writer = new StreamWriter(stream))
    {
        writer.Write("GET /\r\n HTTP/1.0\r\n Host: www.google.com\r\n\r\n");
        writer.Flush();
        using (var reader = new StreamReader(stream))
        {
            Char[] readBuff = new Char[256];
            int count = reader.Read(readBuff, 0, 256);

            Console.WriteLine("\nThe HTML contents of page the are  : \n\n ");
            while (count > 0)
            {
                String outputData = new String(readBuff, 0, count);
                Console.WriteLine(outputData);
                count = reader.Read(readBuff, 0, 256);
            }
        }
    }
}
catch (Exception e)
{
    MessageBox.Show(e.Message);
}

I get a 302-response for every website I try. Is this problem due to my request? Or possibly due to the SOCKS-Proxy ?

If you need the code for establishment of SOCKS-Proxy and/or TCP-connection to host just ask. But I thought it was irrelevant.

Thanks!

You have an erroneous line break in your request. The HTTP version needs to be on the same line as the method and resource being requested. Otherwise the proxy/server will think you are an old HTTP 0.9 client instead of an HTTP 1.0 client.

Change this:

writer.Write("GET /\r\n HTTP/1.0\r\n Host: www.google.com\r\n\r\n");

To this:

writer.Write("GET / HTTP/1.0\r\nHost: www.google.com\r\n\r\n");
