String[] arr1 = coll.AllKeys;
for (loop1 = 0; loop1<arr1.Length; loop1++)
{
Response.Write("Key: " + arr1[loop1] + "<br>");
// Get all values under this key.
String[] arr2=coll.GetValues(arr1[loop1]);
for (loop2 = 0; loop2<arr2.Length; loop2++)
{
Response.Write("Value " + loop2 + ": " + Server.HtmlEncode(arr2[loop2]) + "<br>");
}
}
Dim loop1, loop2 As Integer
Dim arr1(), arr2() As String
Dim coll As NameValueCollection
' Load Header collection into NameValueCollection object.
coll=Request.Headers
' Put the names of all keys into a string array.
arr1 = coll.AllKeys
For loop1 = 0 To arr1.GetUpperBound(0)
Response.Write("Key: " & arr1(loop1) & "<br>")
arr2 = coll.GetValues(loop1)
' Get all values under this key.
For loop2 = 0 To arr2.GetUpperBound(0)
Response.Write("Value " & CStr(loop2) & ": " & Server.HtmlEncode(arr2(loop2)) & "<br>")
Next loop2
Next loop1
