socket connection behind proxy

[Atta Ullah]

I am trying to send http request to various sites with following message But get following response .   Request was GET /test HTTP/1.0\r\n\r\n   And response was   HTTP/1.0 302 Redirect Pragma: no-cache Cache-Control: no-cache Content-Length: 0 Connection: close Location: http://proxy.ascertia.com.pk:4080/nohost   Can anyone tell what it means and why not the sending web page.   And also what additional I have to do to create TCP socket connection working behind proxy with http or https.
