Don't ask me why (yet) but...

> a = cgi['a']
a = cgi['a'].dup

and...

22:47 fred@balvenie:~/> ruby test.rb
(offline mode: enter name=value pairs on standard input)
a=hi
Inserting value a=bye into the database.
What was actually inserted into the database: bye

...

It seems that CGI does horrible, horrible things to its strings :

require 'cgi'
cgi = CGI.new('html4')

a = cgi['a'] #.dup
b = cgi['a'].dup

puts "A :"
a.sub!(/hi/, 'bye')
puts a.to_s
puts a.inspect
puts a.class

puts "B :"
b.sub!(/hi/, 'bye')
puts b.to_s
puts b.inspect
puts b.class

Gives :

22:53 fred@balvenie:~> ruby test.rb
(offline mode: enter name=value pairs on standard input)
a=hi
A :
hi
"bye"
String
B :
bye
"bye"
String

Ugh !
