The ncgi package provides commands that manipulate [CGI] values. These are values that come from Web forms and are processed either by [CGI] scripts or web pages with embedded Tcl code. Use the ncgi package to query these values, set and get [cookies], and encode and decode www-url-encoded values. (From the man page [http://tcllib.sourceforge.net/doc/ncgi.html])

Documentation can be found at http://tcllib.sourceforge.net/doc/ncgi.html

Undocumented, but fairly important, is the need to call ::ncgi::header (or ::ncgi::redirect) after ::ncgi::setCookie, else the cookie does not set. Jan. 13, 2010 

======
#!/usr/bin/env tclsh8.4
package require ncgi
::ncgi::setCookie -name test -value THisIsAGoodCookie -domain yourdomain.com -expires "july 20, 2010" -path /
#NOTE: Must use ncgi::header else cookie never sets. 
#ALSO: The following two are similar, but not the same.
#puts "Content-Type: text/plain\n"
::ncgi::header

puts "cookie: [::ncgi::cookie test]"

recently on comp.lang.tcl, [aku] mentioned that ncgi came about by starting with [Don Libes]' [cgi.tcl] and breaking the
code into namespaces and 3 modules.
