Recursive WebRequest.Create()

The WebRequest class implements IWebRequestCreate and hence, a method
Create.
This method has two other overloads, one of which is a private method.
Here's how it looks:
public static WebRequest Create(string requestUriString)
public static WebRequest Create(Uri requestUri)
private static WebRequest Create(Uri requestUri, bool useUriBase)
Both the public overloads with a single argument internally call the
private overload with the second parameter as false. The implementation
of the private method is given below:
private static WebRequest Create(Uri requestUri, bool useUriBase)
{
string text1;
WebRequestPrefixElement element1 = null;
bool flag1 = false;
if (!useUriBase)
{
text1 = requestUri.AbsoluteUri;
}
else
{
text1 = requestUri.Scheme + ':';
}
int num1 = text1.Length;
ArrayList list1 = WebRequest.PrefixList;
for (int num2 = 0; num2 < list1.Count; num2++)
{
element1 = (WebRequestPrefixElement) list1[num2];
if ((num1 >= element1.Prefix.Length) &&
(string.Compare(element1.Prefix, 0, text1, 0, element1.Prefix.Length,
true, CultureInfo.InvariantCulture) == 0))
{
flag1 = true;
break;
}
}
if (!flag1)
{
throw new
NotSupportedException(SR.GetString("net_unknown_prefix"));
}
return element1.Creator.Create(requestUri);
}
I was surprised to see the last statement of this private overload
calling one of the other public overloads. Isn't this recursive, or am
I missing something here?
