Preciso formar um post da seguinte forma:

 

POST /xmlfeed HTTP/1.0
Host: myserver.domain.com:19900
Content-Length: 221
Content-Type: application/x-www-form-urlencoded

feedtype=full&datasource=sample&data=%3C%3Fxml%20
version%3D%221.0%22%20encoding%3D%22UTF8%22%3F%3E%0A%3C%21
DOCTYPE%20gsafeed%20PUBLIC%20%22-//Google//DTD%20GSA%20
Feeds//EN%22%20%22%22%3E%0A%3Cgsafeed%3E%0A%3C/gsafeed%3E

 

Mas me retorna sempre o erro "400" = Bad Request

 

Não consigo identificar o que estou fazndo de errado.

 

Alguém poderia ajudar??

O erro ocorre em qual linha? Eu acho que o problema não esta no código e sim na url.

A URL esta correta pois utlizo ela pra envio de um outro sistema que desenvolvi em Python,

mas desconfio que esta no envio dos parametros ou em algum texto que nao esta codificado.

 

 

será que alguém poderia ajudar?

 

abraços

 

ocorre sempre na seguinte linha:

 

_myHttpWebResponse = (HttpWebResponse)myRequest.GetResponse();
