handle StatusCode==302 when using HttpWebrequest - c# - c#-3.0

Question

I have a windows app that I am trying to build to simulate an upload to a web app. The project is in C# 3.0.
When using Fiddler, I can see the following
/login page - 200 code
enter pwd/uname
/home page - 302 code
/home page - 200 code
/upload page [This page has simple multi-part form post where user can select at max 2 files to upload] - 200 code
/fileprocessed page - 302 code
/fileprocessed page - 200 code
When i use HttpWebrequest with webresponse object, i get
/login page - 200 code
enter pwd/uname
/home page - 200 code
/upload page [This page has simple multi-part form post where user can select at max 2 files to upload] - 200 code
/fileprocessed page - 302 code
I do have SetAutoRedirect to true
My code is
Stream requestStream = request.GetRequestStream();
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Write(buffer, 0, buffer.Length);
FileStream stream2 = new FileStream(filePath, FileMode.Open, FileAccess.Read);
byte[] buffer = new byte[0x1000];
int count = 0;
while ((count = stream2.Read(buffer, 0, buffer.Length)) != 0)
{
requestStream.Write(buffer, 0, count);
}
bytes = Encoding.ASCII.GetBytes("\r\n--" + str2 + "--\r\n");
requestStream.Write(bytes, 0, bytes.Length);
requestStream.Close();
stream.Close();
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
if(response.StatusCode == HttpStatusCode.Found)
{
string newURL = response.Headers["Location"];
}
How do I avoid the 302 error or how do I account for it wherein I can do a successful form post to simulate the upload

Answer 1

I had a similar case, where I recieved 302 status codes when I expected 200 to be returned (like in Fiddle or Firebug: net tab). I was able to solve the problem by giving an user agent specification to the HttpWebResponse
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0) Gecko/20100101 Firefox/4.0";
