I found this article:

But I just don't know how to selectively clear cookies only, or selectively clear the cache of a single domain. Any help would be greatly appreciated.

When I specify null or an empty set for the url, I don't seem to get any cookies let alone all of them. This is the code I'm using:

public static void clearCookies()
{
string szURL = "";
int dwSize = 256;
StringBuilder lpszData = new StringBuilder(dwSize);

if (!InternetGetCookie(szURL, null, lpszData, ref dwSize))
{
if (dwSize < 0)
return;
lpszData = new StringBuilder(dwSize);
InternetGetCookie(szURL, null, lpszData, ref dwSize);
}

MessageBox.Show("Cookie: " + lpszData);
}
