Now, you might be wondering, what does he mean, Don\\\'t skimp on the variables? Well, often times it is more efficient to use variables to store results from ADO queries or from objects, and then reference the variable as opposed to continuously referencing the object. For example, you could do this: If Request.QueryString("Name") = "Frank" Then ... End If If Request.QueryString("Name") = "Steve" Then ... End If Response.Write("Your name is " & Request.QueryString("Name")) Each time you use the Request object, ASP has to go read the QueryString variable name. You can reduce this to having to just read this once by doing the following: Dim strName strName = Request.QueryString("Name") If strName = "Frank" Then ... End If If strName = "Steve" Then ... End If Response.Write("Your name is " & strName) Plus, I personally think the above scenario is easier to read. It\\\'s easier, I think, to mentally associate strName to be the user\\\'s name as opposed to associating Request.QueryString("Name") as the user\\\'s name.
