I use this for my personal reference as I can never remember them all.
Check it out if you like. Here is the code to create your own.
<script runat="server">
Protected Sub Page_LoadComplete(ByVal sender As Object, ByVal e As System.EventArgs)
Dim item
For Each item In Request.ServerVariables
litDisplay.Text += "<tr><td>" & item & "</td><td>" & Request.ServerVariables(item) & "</td></tr>"
Next
End Sub
</script>
<table rules="rows" border="1">
<asp:Literal runat="server" ID="litDisplay" />
</table>
