TWS is a database-driven web server in a self-contained executable. Features include:
The goal of TWS is to be both flexible and very easy to use. To this end, the design uses a number of innovative features:
|Stand-alone||Everything, both web-server and SQL database engine, is contained in a single executable. So installation is a snap. All you have to do is copy the binary onto the disk drive of the host machine. There are no worries about compatible libraries or DLLs and no hassles setting up and configurating a separate RDBMS.|
|Secure||By default, the server places itself in a chroot jail and converts to an unprivileged user upon startup. And conservative coding practices are used to make the server resistant to attack.|
|Cross-platform||TWS can be compiled for either Windows or Unix, so it will probably work on any computer that happens to be at hand. You do not have to have a particular version of a particular operating system to use TWS.|
|Configurable Online||The TWS web server uses a single human-readable configuration file, but you never need to look at it or edit it. All configuration is done using web-pages that are built into the web server itself.|
|Extensible||TWS normally serves content from disk, like any other web server. But TWS also contains content in a ZIP archive appended to the TWS executable. You can add new content files to this ZIP archive to implement custom, self-contained, stand-alone web applications.|
|Embeddable||The core HTTP engine used by TWS is modular and implemented in just two source files. It is very easy to embed this HTTP engine inside another application to give that application the ability to report its status or to be configured dynamically using a web browser.|
|Lightweight||The TWS web server uses surprising little memory and CPU time. So you don't have to hunt around for a big hefty server to run it on. Any old 486 will probably suffice.|
TWS was released as beta on Feb 17, 2001. The same code base has been used internally (behind a firewall) for about a year, so it has been tested. But additional testing on different platforms and under adversarial conditions is needed before it is pronounced "stable".
A change log is available.
