That is a Vignette CURL (complex URL).
Vignette StoryServer is a page engine that embeds TCL instead of PHP. It also works in an odd, seemingly backwards way: it is invoked as a 404 error handler.
The URL you are viewing maps to a real filename, 0,9429,2133218,00.html. If the file is missing, StoryServer handles the error. It analyzes the URL, extracts the relevant numbers, queries the database, builds the page, potentially stores the results in the filesystem and then serves the result.
As I recall, the first number is a cache flag (0 means cache the result in the filesystem). The second number is a template ID; the template, a mixture of HTML and embedded TCL commands, is stored in the database for evaluation. The third number is an object ID that is passed to the template. The final number is a browser-specific version flag that lets the system support special formatting for alternative browsers.
Vignette systems start around $200,000, including the underlying database schema and some other tools. You can create much of the functionality that I just described by writing a 404 error handler in PHP. The query string is available (read the PHP documentation) and you would have to parse it manually.
