Thanks for the example. I had seen your example earlier and had tried
it and always get to one particular point where I cannot seem to get
beyond. There are two hidden fields both called web.fixed_value s that
appear to be something like a view state but the page is shtml. I am
and have been able to pull down the site, etc. but everytime I try and
post my data (with or without the web.fixed_value s) I always get the
response Method Not Allowed. Below is the code I am using along with
the sire I am trying to access with my account. ANy further help on
this would be greatly appreciated.
private void Page_Load(objec t sender, System.EventArg s e)
{
string LOGIN_URL = "http://augustachronicl e.com/login.shtml";
string cookieAge = "31536000";
try
{
HttpWebRequest webRequest = WebRequest.Crea te(LOGIN_URL) as
HttpWebRequest;
StreamReader responseReader = new
StreamReader(we bRequest.GetRes ponse().GetResp onseStream());
string responseData = responseReader. ReadToEnd();
responseReader. Close();
// get the web fixed values
string fixedvalue1 = ExtractFixedVal ues1(responseDa ta);
string fixedvalue2 = ExtractFixedVal ues2(responseDa ta);
string postData = String.Format(" web.fixed_value s={0}&web.fixed _values={1}&ACT ION=Login&USER= {2}&PASS={3}&co okie_age={4}",f ixedvalue1,fixe dvalue2,userNam e,
password, cookieAge);
// have a cookie container ready to receive the forms auth cookie
CookieContainer cookies = new CookieContainer ();
// now post to the login form
webRequest = WebRequest.Crea te(LOGIN_URL) as HttpWebRequest;
webRequest.Meth od = "POST";

Scott,
FYI - that was one of the best articles on the subject I ever read.
I was completely stuck on this issue about 6 months ago and I implemented it
straight away using the concepts you presented here.
Excellent work and explanation.
