The Neowebscript-SA server in the Tcl Add-on can do 'asp-like' processing.
Of course, you write your application code in Tcl, embedded in the
web pages. For a simple example, start the Neowebscript server, and
access the server with a browser. The server recognizes
<nws>.....</nws> tags in html pages. Any text between these tags gets
interpreted with Tcl's 'subst' command, which will replace $xxxx with
the value of a Tcl variable, and [ ] will cause a Tcl script to be
interpreted. E.g.
<html><body>
<p> the current time is <nws> [clock format [clock seconds]] </nws>
<nws> <p> and your surfing from ip address: $webenv(REMOTE_ADDR) </nws>
</body></html>
By default, Tcl commands are executed in a 'safe' interpreter (scripts
cannot exec other programs, cannot delete files, etc.) If you want
that behavior, you can modify the conf/init.tcl script to add 'alias commands'
in the safe interpreter that execute commands is the master interpreter.
E.g., you can have a 'exec' alias that first checks for a valid list of
OS commands, and only execute that command if it is part of the permitted list.
