The first time a user accesses to a our pages some connections and disconnections took place. During this process the server and the client will interchange information to identify each other. Due to this exchange of information our server will be able to identify a specific user and this information may be use to assign specific information to each specific client. This relationship between computers is call a session. During the time a session is active, it is possible to assign information to a specific client by using Session method. We will use an example to explain this method:

One of the first things we do in the script is assign the form fields that have been submitted to program variables. By assigning these values to variables we cut down on the amount of typing required and we reduce somewhat the possibility of making coding errors. We should note that this is not a requirement for the script; it simply adds a convenience to our coding chore. We can refer to these values through their variable names rather than the more lengthy Request.Form Collection names.

Fetching records in an optimized way actually has many variations. We will list most of them here, provide code sample and typical timings for fetching and displaying records. These timings reveal an interesting behavior. Even if a script reports it ran in say, 7 seconds, that refers to the time that script received from the CPU. So that if 7 scripts take 8 seconds each there may be hundreds or thousands of scripts running on the server that are sharing the CPU. User #1 may see a 7 second result in 21 seconds, so their 7 second report reflects the time spent on the server/CPU for the script and the fact that 14 seconds of other stuff was executed round-robin with the rest of the scripts, not the time since the script started.

 This article contains a full VBS source code of a Base64 decode function (base64 decoder). You can use the function, for example, to decode basic http authentication info - username and password, or to decode incomming emails.
      
  Base64Decode VBS function can only work with small amount of data - VBS does not enable to work with buffers to improve performance. Consumed processor time rapidly grows with source data length (by square). Please use Base64 property of ByteArray object (ScriptUtilities library, C++ COM object, comercial) if you want to work with large data. ByteArray lets you also work with codepage (charset) conversions and provides binary file access and binary-to-string conversion. ScriptUtilities is also available with source code.
