This is a pure-Tcl implementation of an HTTP protocol server. It runs as
|
|
a script on top of a vanilla Tcl interpreter using tcllib scripts and,
|
|
optionally, two binary libraries (crypt and limit).
|
|
|
|
The Tcl I/O system provides event-driven I/O facilities and a primitive
|
|
that copies data from one I/O channel to another. The server does the
|
|
HTTP protocol handling and then simply directs the I/O system to blast
|
|
data from disk to a network socket. The server has suprisingly good
|
|
performance because of Tcl's sophisticated I/O system.
|
|
|
|
The HTTP protocol is perhaps the least interesting aspect of the server.
|
|
The cool stuff is the framework for generating dynamic page content, and
|
|
the support for embedding the server directly into legacy applications
|
|
to "web-enable" them.
|
|
|
|
A Tcl-based web server is ideal for embedding because Tcl was designed
|
|
to support embedding into other applications. The interpreted nature of
|
|
Tcl allows dynamic reconfiguration of the server. Once the core
|
|
interface between the web server and the hosting application is defined,
|
|
it is possible to manage the web server, upload Safe-Tcl control
|
|
scripts, download logging information, and otherwise debug the Tcl part
|
|
of the application without restarting the hosting application.
