Ciao é semplicissimo:
info = Request.ServerVariables[x]
dove x é il nome della variabile che ti interessa.
Es. "HTTP_INFO", "ALL_RAW"
-----------------------------------------------------------
Se le vuoi vedere tutte ecco gli script per VB e C# recuperati dall' MSDN:
[Visual Basic]
Dim loop1, loop2 As Integer
Dim arr1(), arr2() As String
Dim coll As NameValueCollection
' Load ServerVariable collection into NameValueCollection object.
coll=Request.ServerVariables
' Get 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) & ": " & arr2(loop2) & "<br>")
Next loop2
Next loop1
[C#]
int loop1, loop2;
NameValueCollection coll;
// Load ServerVariable collection into NameValueCollection object.
coll=Request.ServerVariables;
// Get names of all keys into a string array.
String[] arr1 = coll.AllKeys;
for (loop1 = 0; loop1 < arr1.Length; loop1++)
{
Response.Write("Key: " + arr1[loop1] + "<br>");
String[] arr2=coll.GetValues(arr1[loop1]);
for (loop2 = 0; loop2 < arr2.Length; loop2++) {
Response.Write("Value " + loop2 + ": " + arr2[loop2] + "<br>");
}
}
Ciao e buon lavoro
