ASP.NET Futures: Generating Dynamic Images w/ HttpHandlers Gets Easier

Sun, 24 Aug 2008 09:31:12 GMT

I've done a lot of HttpHandlers that generate images. It's usually pretty tedious. When I was working banking, I wrote an example HttpHandler that would take two Check Images (back and front) and composite them into a single image on the server side, then serving up the composite. Usually you're messing around in with MemoryStreams and Images, and then you serialize the result out to the Response.OutputStream, making sure the MIME Types are set appropriately. If you're really clever, you'll remember to do some client-side and appropriate caching, but I rarely see that in the wild.

How to use the IHttpAsyncHandler in ASP.NET

Sun, 29 Jun 2008 20:21:17 GMT

Basically, the IHttpAsyncHandler interface allows you to serve content asynchronously from a HTTP handler. This is great when you need to free up the worker thread to do processing like IO work etc. ASP.NET actually uses fewer threads when it runs asynchronously, which is great for performance and scalability. That's because each thread is returned much faster to the thread pool.

In this article, I will discuss a technique for distributing compressed website assets (CSS and javascript files) using ASP.NET. Compressing these files reduces bandwidth usage, which means decreased costs on server traffic. (Take 10,000 viewers/users and up, and the savings become significant.)

Streaming a vCard on the Fly in ASP.NET with a Custom httpHandler

Sun, 23 Sep 2007 21:25:06 GMT

To continue with my series on httpHandlers I want to cover how to stream a vCard to the user based on a parameter. First let me say that I grabbed the code for the .NET vCard class from a CodeProject.com article. There is also a corresponding vCalendar class. The idea behind a vCard is it is a standard format for sharing information about a person that can be imported directly to applications like Outlook.

HttpHandler and "Save As" prompt

Wed, 28 Mar 2007 04:16:01 GMT

These days I work a lot with Reporting Services and an ASP.NET application which serve reports on an aspx page. The problem is pdf is a known file type so the browser open Adobe Acrobat instead of asking the user to save the file. I knew this is possible so I was happy to google and find this entry from Andrew L. Van Slaars.
