On the desktop the VFX Forth Professional editions, and the embedded
Forth 7 cross compilers, include the PowerNet web servers. These use
ForthScript (yes, just Forth) for server-side scripting. Here's a
simple example:

<html>
<head><title>Test form response by ASP</title></head>
<body>
<h3>Thank you</h3>
<p>The form response has been processed using ASP and ForthScript
by the PowerNet Web Server. You can see the code in the file
<i>TestPages\thanks.asp</i>, which is the file that generated
this page.
</p>
<% language=forthscript %>
<br><h3>Your responses were:</h3>
<p>Name : <% s" sname" .qstring %> </p>
<p>Email: <% s" smail" .qstring %> </p>
<p>State: <% s" state" .qstring %> </p>
<p>You pressed the <% s" send" .qstring space %> button</p>
</body>
</html>

The code between <% and %> is just Forth source code which is
executed on the server when the page is served.
  s" sname" .qstring
displays the value of of a connection variable called SNAME.
