But when CF queries a database and the column has no data (null) you get back an empty string - so that's really very consistent... > Good call. At the *very least* there should be a function to "go get ALL > the webserver's CGI variables NOW". At least the names of them, anyhow. I'm not entirely sure such a function is supported by most web servers. The problem is that CGI variables are so specific to each web server that you can't write web server neutral code unless you really only stick to a few very basic CGI variables. And even then, most of the really core ones are accessible through the J2EE getPageContext().getRequest() machinery (which may or may not be safer). The set of available CGI variables changes with each web server and often with different versions of a single web server. It also depends on how you're connecting the web server to CF. Even with IIS I believe there are two different ways to configure the connector, yes? The bottom line is that you really can't rely on CGI variables for much so they should all be considered "caveat programmer"... -- Sean A Corfield -- http://www.corfield.org/ Team Fusebox -- http://www.fusebox.org/ Breeze Me! -- http://www.corfield.org/breezeme Got Gmail? -- I have 5 invites to give away!
