mod_dtcl is an implementation of server-parsed tcl for the Apache web server.  It is fast, light, simple and easy to use.  More information may be had at http://tcl.apache.org/mod_dtcl/

From the [Tcl chatroom] on 2001-11-05:

Micailah: does anyone know if mod_dtcl works on windows 98 if not is there a tcl module for apache server for win98? 

[Pat Thoyts]: Sorry - I was elsewhere - I use mod_dtcl on win98 myself. There are some funny things to do to install it. 
One is to rename the file to ApacheModuleDtcl.dll and place it into the modules subdirectory of apache. 
Then add the following line to httpd.conf: 
 LoadModule dtcl_module modules/ApacheModuleDtcl.dll 
near the modules section 
plus these lines near the other AddHandler lines: 
 AddType application/x-httpd-tcl .ttml 
 AddType application/x-dtcl-tcl .dtcl 

To test put something like this in htdocs/test.dtcl 

 package require html
 puts [eval {
     html::init
     html::author "Me <self@localhost>"
     html::description "test out the Dtcl module for Apache."
     html::head "DTcl Test Page"
 }]
 
 puts [html::h1 [html::getTitle]]
 puts "[array get tcl_platform]"
 puts [html::end]

and browse to it.
