strKeyName = Request.ServerVariables.Key(3) strKeyValue = Request.ServerVariables.Item(strKeyName)
If, on the other hand, you know that the third element's key name is "QUERY_STRING," you could simply use the following code to retrieve the value of that element:
strKeyValue = _ Request.ServerVariables.Item("QUERY_STRING")
strKeyValue = Request.ServerVariables("QUERY_STRING")
The number of elements in the collection.
