Yes (see notes for more) 1. All CGI variables that exist are stored in a structure called CGI. 2. A len() should be used to determine if a CGI variable exists because (for some reason) it will ALWAYS exist. You can test this by outputting the following: <CFOUTPUT> #cgi.thisisafakevar# - #len(cgi.thisisafakevar)# </CFOUTPUT> 3. you can see a 'true' list of CGI variables by using this code: <CFLOOP collection="#cgi#" item="i"> <CFOUTPUT>#i# #cgi[i]#</cfoutput><BR> </cfloop>
