C# - HttpWebResponse redirect to external URL -

i'm trying achieve following:

• i'm building mvc website me automatically logon site.
• websitea call websiteb using httpwebrequest.
• websitea send details of user through headers (request.headers.add)
• websiteb handle user authentication , internally redirect page granting access user.

i've managed achieve part of i'm stuck in displaying redirection return. knows if can achieved?

here code gets called in websitea app:

        [httppost]         [outputcache(nostore = true, duration = 0, varybyparam = "*")]         public actionresult login(mymodel model)         {             httpwebrequest request = (httpwebrequest)webrequest.create("http://websiteb/login.aspx");             request.allowautoredirect = true;             request.method = "post";             request.headers.add("myusertologon", model.user); //i'm sending user through headers             string postdata = "this test";             byte[] bytearray = encoding.utf8.getbytes(postdata);             request.contenttype = "application/x-www-form-urlencoded";             request.contentlength = bytearray.length;             stream datastream = request.getrequeststream();             datastream.write(bytearray, 0, bytearray.length);             datastream.close();              //get response login page             httpwebresponse response = (httpwebresponse)request.getresponse();              // display status.             console.writeline(((httpwebresponse)response).statusdescription);             datastream = response.getresponsestream();             streamreader reader = new streamreader(datastream);             string responsefromserver = reader.readtoend();             console.writeline(responsefromserver);              reader.close();             datastream.close();             response.close();              //what here? want go redirected page websiteb/page1.aspx             //see code below websiteb.              return null;         } 

in websiteb have code redirection when user logged in:

        .......         users = request.querystring["myusertologon"];         .......          private void login(string user)         {             grantuser(user, session.sessionid);              httpcookie mycookie = new httpcookie("test");             mycookie .expires = datetime.now.addminutes(10);             response.cookies.add(mycookie);             response.addheader("mycookie ", mycookie .value);              response.redirect("websiteb/page1.aspx");         } 

any appreciated.

i had same problem sites.

you can't use redirect because done iis , never receive authentication cookies websiteb.

in case returning view instead of redirect worked. , redirect on websitea after setting cookies

also seems need add cookie container request cookies back.

here may code

landing site

 [httppost]     public actionresult login(string accountid)     {          var url = "http://...."          var request = (httpwebrequest)webrequest.create(url + "/account/wamlogin/");          request.headers.add("user", accountid);         request.cookiecontainer = new cookiecontainer();          var response = (httpwebresponse)request.getresponse();          foreach (cookie cook in response.cookies)         {             response.cookies.add(new httpcookie(cook.name, cook.value) { expires = cook.expires, httponly = cook.httponly, domain = cook.domain });         }          return new redirectresult(url);     } 

here websiteb code

[allowanonymous] public virtual actionresult wamlogin(string returnurl, string id) {     var accountid= request.headers["user"];      .....      return view(mvc.account.views.login); } 

hope you
