ASP.NET–What is ISAPI ?/What is CGI?/ Advantage Of ISAPI Over CGI

    * What is CGI?

It is a gateway for transferring information between a World Wide Web server and a CGI program.

A CGI program is any program designed to accept and return data that conforms to the CGI specification. The program could be written in any programming language, including C, Perl, Java, or Visual Basic or ASP.NET.

CGI programs are the most common way for Web servers to interact dynamically with users. Many HTML pages that contain forms, for example, use a CGI program to process the form’s data once it’s submitted. Another increasingly common way to provide dynamic feedback for Web users is to include scripts or programs that run on the user’s machine rather than the Web server. These programs can be Java applets, Java scripts, or ActiveX controls. These technologies are known collectively as client-side solutions, while the use of CGI is a server-side solution because the…

Functional Programming in C# – Higher-Order Functions

Andrew Matthews

  1. Functional Programming – Is it worth your time?
  2. Functional Programming in C# – Higher-Order Functions

This is the second in a series on the basics of functional programming using C#. My topic today is one I touched on last time, when I described the rights and privileges of a function as a first class citizen. I’m going to explore Higher-Order Functions this time. Higher-Order Functions are functions that themselves take or return functions. Meta-functions, if you like.

As I explained last time, my programming heritage is firmly in the object-oriented camp. For me, the construction, composition and manipulation of composite data structures is second nature. A higher-order function is the equivalent from the functional paradigm. You can compose, order and recurse a tree of functions in just the same way as you manipulate your data. I’m going to describe a few of the techniques for doing that using an example…

Functional programming – Is it worth your time?

Andrew Matthews

Short Answer: Yes!

Regular readers of the The Wandering Glitch know I focused lots of attention on LINQ and the new wave of language innovation in C# 3.0. I’m intrigued by functional programming in C#. At university, I focused on languages like C, C++, Eiffel and Ada. I’ve never since needed to learn functional programming techniques – who uses them, after all? Functional programming had always seemed like a distant offshoot of some  Bourbakiste school of mathematical programming unconcerned with practical issues of software development. Don’t get me wrong – I find that attractive, but it was always hard to justify the time, when there was so much else of practical worth that I needed to study. So the years passed, and I never came near. Functional programming was suffering from bad PR. But times change.

A fundamental change is under way in how we develop software. Declarative, Functional, Model-driven…

Survey Results: The Current State of Application Integration

Richard Seroter's Architecture Musings

Before my recent trip to Europe to discuss technology trends that impact application integration, I hunted down a bunch of smart integration folks to find out what integration looks like today. What technologies are used? Is JSON climbing in popularity? Is SOAP use declining? To find out, I sent a survey to a few dozen people and got results back from 32 of them. Participants were asked to consider only the last two years of integration projects when answering.

Let’s go through each question.

Question #1 – How many integration projects have you worked on in the past 2 years?

Number of answers: 32

Result: 428 total projects


Individual answers ranged from “1” to “50”. Overall, seemed as if most integration efforts are measured in weeks and months, not years!

Question #2 – What is the hourly message volume of your typical integration project?

Number of answers: 32
