C# Set Credential Only Once For Multiple Requests

Question

I'm writing a program in visual studio 2010 using C# .Net.

The program will access multiple parts of the website (different urls), and I'm using HttpWebRequest and NetworkCredential to set username and password.

Right now, every time I send in a request, I have to set the credential. Is there a way to set the credential only once through out the whole process?

public void setCredential(string url)
{    
    //set username and password    
    //and get response    
}

public void Main()    
{ 
    string[] URLs= { url1, url2, url3 };    
    foreach (string url in URLs)    
    {    
        setCredential(url);    
    }
}

Like I mentioned, by doing it this way, every time I go to a new url I will have to set the credential, which makes it slow sometimes.

I tried to set the credential outside the foreach loop but then I was not able to get response for url2 and url3.

I'm wondering if there's a better way to do it?

-- Edit 10:26am --

Sorry if I'm not clear.

What I meant is that every time I try to access a url, I had to re-send the username and password over to the server.

So for the sample code, I will have to send the username and password 3 times for 3 different url.

I would like to know if I can send the username and password only once and access all 3 different urls.

ps. All 3 urls are accessible with the same username and password.
