How does the following code need to be modified to send the WebRequest via a specified proxy server and port number?
Dim Request As HttpWebRequest = WebRequest.Create(url)
Request.Method = "POST"
Request.ContentType = "application/x-www-form-urlencoded"
Using writer As StreamWriter = New StreamWriter(Request.GetRequestStream())
writer.Write(params)
End Using
use this code from MSDN :
Dim myProxy As New WebProxy()
myProxy.Address = New Uri("proxyAddress")
myProxy.Credentials = New NetworkCredential("username", "password")
myWebRequest.Proxy = myProxy
A WebRequest object has a 'Proxy' property of IWebProxy. You should be able to assign it to use a specified proxy.
Request.Proxy = New WebProxy("http://myproxy.com:8080");
If the proxy is not anonymous, you will need to specify the Credentials of the WebProxy object.
For example, if your Web server needs to go through the proxy server at http://255.255.1.1:8080,
Dim Request As HttpWebRequest = WebRequest.Create(url)
'Create the proxy class instance
Dim prxy as New WebProxy("http://255.255.1.1:8080")
'Specify that the HttpWebRequest should use the proxy server
Request .Proxy = prxy
Request.Method = "POST"
Request.ContentType = "application/x-www-form-urlencoded"
Using writer As StreamWriter = New StreamWriter(Request.GetRequestStream())
writer.Write(params)
End Using
