Lovingly crafted simplicity.
CGI can get complex when you include library after library, so let's do it by hand:
#!/usr/bin/tclsh puts "Content-type: text/plain\n" puts eogieogeig
The most basic cgi, all it does is display some text, not even html! But hey, if you're this far, your server is set up, your permissions on your cgi file are correct, and that's half the battle.
#!/usr/bin/tclsh puts "Content-type: text/html\n" puts { <html> <head> <title>wonderz</title> </head> <body> aloha! </body> </html> }
Great! You're sending them html now. Notice the Content-type header.
#!/usr/bin/tclsh puts "Content-type: text/plain\n" parray env
Wow! Text again, but this time we're dumping out our environment variables, and thats the guts of interfacing to the server, hence the term Common Gateway Interface.
