Re: Automating login to website with IIS basic authentication - MSDN Forums

Hi Rick,

Here is the link I used to learn about doing this:

http://www.port80software.com/support/articles/authenticationiniis

I can supply you with the code I used to send the user and pass to a site with IIS basic authentication setup but it might be a little confusing since it's modified for my particular application. Also some variable declarations are missing since they are in other parts of the code but this should point you in the right direction... I used the webbrowser object(AxWebBrowser1) to do the actual redirect.

byte[] data;
object objheader;
ASCIIEncoding encoding= new ASCIIEncoding();
data = Encoding.UTF8.GetBytes("");
object objdata = data;
object objnull = "";
string userPass = "myPassword";

//then convert to bytes
byte[] AuthData=System.Text.UnicodeEncoding.UTF8.GetBytes(userPass);
Base64Encoder myEncoder=new Base64Encoder(AuthData);
StringBuilder sb=new StringBuilder();
//Dos would not transfer \r properly from .bat file so we had to recreate it in c#
sb.Append(this.webParams.Substring(0,this.webParams.LastIndexOf("Authorization:")) + "\r");
//reapply the following string which was taken out during parsing and
//addition of \r for carriage return which is neccessary for the proper http header formation
sb.Append("Authorization: Basic ");
//add the new base64 encoded password
sb.Append(myEncoder.GetEncoded());
//apply string to object
objheader = "Content-Type:application/x-www-form-urlencoded\rUser-Agent: MSIE\r" + sb.ToString();

/for debug
//MessageBox.Show("Content-Type:application/x-www-form-urlencoded\rUser-Agent: MSIE\r" + sb.ToString());
