IBM Lotus Domino
Have you ever wanted an easy way to see what HTTP Header and CGI variables were available to a Domino Wev Server? I know much of what's available is documented, but when I started learning about BlackBerry web development, I wanted a way to be able to see in real-time what the Domino server knew about the BlackBerry device connecting to it. To help me figure this out, I created a little sample Domino database that dumped a bunch of information the Domino Server knows about a User-Agent (the browser) back to the browser screen making the request.
Here's a sample screen shot from a BlackBerry device illustrating what the application looks like:
I just posted an article about the application and the Domino database to my BlackBerry Development Fundamentals site. Check it out when you get a chance (only if you're interested of course).
