I do a LOT of interviewing here, and for a while we were hiring ASP.NET people. Here's some of the questions that I asked them. I came up with these questions because you'd "just know" this stuff if you spent time working on a REAL WORLD ASP.NET site - through design, development, debugging, production debugging, and deployment. Do they suck? Did I miss any? How do you think people did? From constructor to destructor...

Compression is a very "cheap and easy" way to improve responsiveness of your site. Here is an excerpt from an excellent white paper: High Performance Web Sites: The Importance of Front-End Performance There are three main reasons why front-end performance is the place to start.

If you have multiple controls in your ASP.Net, especially third-party ones, which in turn have a dependency on another third-party component, you are in for a world of pain if different controls use different versions of the same third-party component. Since your app has only one "bin" folder where all the assemblies reside, putting one version of the third-party component will break controls that rely on the other version. Luckily, the .Net developers...

I also see this asked often on the ASP.NET forums and I thought it would be worthwhile to address the question here for a reference point. The quick answer is httpModule works with the web application as sort of an adjunct to the request pipeline because modules generally add some processing in response...
Custom errors and early error-logging effort In the beginning, webs were just "webs", webs of interconnected links to static HTML pages. Now webs resemble more of communities bustling with activities, with members of different roles, media in all forms and shapes, etc. As a web site grows more complex, the opportunities for errors and exceptions multiply. As it attracts more users, it becomes a bigger target of malicious attacks. Now it has become...

Overview: Like mathematicians, developers talk about their code in aesthetic and sometimes hygienic terms. The code is “elegant,” or it “looks clean,” and sometimes it “smells bad”. I have even heard developers refer to their code as “sexy.” Talking about your code as sexy is surely a sign that you need to get out more! Achieving elegant code is...
