Introduction

There's lots of helpful information about Active Server Pages (ASP) available on this site and other sites. If you have plenty of time to search for the information, you can find answers to most of your questions. But if you want to find out what tools you can use to debug ASP or how to handle errors, you need to do some digging. This article provides an easy way to find information that pertains to ASP, including a short definition of what ASP is, how ASP works, and an alphabetical list of terms and tips that relate to ASP. In the A-to-Z list, you will see a brief description as well as pertinent links to more detailed information (when that information is available). This article is meant to be a "living" document. That means that I plan on updating it with new tips and removing tips that no longer apply. If you are an ASP developer and have a "juicy" tip, send it to me. If I publish it here, you'll get credit and the everlasting gratitude of throngs of other ASP developers.

What ASP Is

Active Server Pages is a programming environment that provides the ability to combine HTML, scripting, and components to create powerful Internet applications that run on your server. If you are already creating Web sites that combine HTML, scripting, and some reusable components, you can use ASP to glue these items together. You can create an HTML interface for your application by adding script commands to your HTML pages and you can encapsulate your business logic into reusable components. These components can be called from script or other components.

How ASP Works

When you incorporate ASP into your Web site, here's what happens:

1.The user brings up a Web site (like MSDN Library) where the default page has the extension .asp.

2.The browser requests the ASP file from the Web server.

3.The server-side script begins to run with ASP.

4.ASP processes the requested file sequentially (top-down), executes any script commands contained in the

file, and produces an HTML Web page.

5.The Web page is sent to the browser.

Because your script runs on the server, the Web server does all of the processing and standard HTML pages can be generated and sent to the browser. This means that your Web pages are limited only by what your Web server supports. Another benefit of having your script reside on the server is that the user cannot "view source" on the original script and code. Instead, the user sees only the generated HTML as well as non-HTML content, such as XML, on the pages that are being viewed.

ASP from A to Z

This section contains a list of terms and tips to help you understand ASP. They are listed in alphabetical order. Scroll down to the topic that interests you or click the letter in the alphabet below to jump down to the section containing the topic. I cribbed, er, I mean, compiled these tips and definitions from a number of sources, including technical articles (listed in the bibliography below), Knowledge Base articles, and a beta version of the Microsoft® Internet Information Server (IIS) 5.0 documentation (I'm so lucky!).

Active Data Objects (ADO) provides a programming model for an OLE-DB data source. It is the database model that ASP uses; however, ASP can use other database access mechanisms. ADO supports the following installable objects, which are often used in ASP files: Command, Connection, Recordset, Field, and Error. Refer to the ADO Web site at /data/ado/ for more information than you can shake a stick at.

Applications

ASP is not just for prototyping. When using ASP as a solution, design your solution as an application instead of designing stand-alone ASP pages. As far as objects are concerned, it's best to take a look at what you need to accomplish and decide what you need, then whether you can buy the objects or will need to create the objects yourself. Take into consideration caching, scalability, reusability, security, and consistency.
