ASP 3.0 also enables buffering by default and optimized the engine for better performance.

[3] ASP uses scripting on the server to generate content that is sent to the client's web browser via HTTP response.

The ASP interpreter reads and executes all script code between <% and %> tags, the result of which is content generation.

In the example below, Response.Write Now() is in an HTML page; it would be dynamically replaced by the current time of the server.

The session object is file based and multiple concurrent read and/or write requests will be blocked and processed in turn.
