A Servlet engine is software that extends/"hooks into" web server software
such as Microsoft's Internet Information Server (IIS), or Apache allowing Java programs (servlets)
to quickly process web browser requests and dynamically generate custom .html
documents.
For instance, ArcIMS generates data for maps requested by users over the web. But, without a Servlet engine, ArcIMS would not be able to receive the requests or to deliver the resulting maps to the user's web browser.
