It can’t, because you made a POST query, so it’s using the [] operator  
to  
store POST data. If you want to access the query string, you can still  
do  
so with CGI#query\_string, but you’ll have to decode it yourself.

(I use this much more simply: I have a script “testframework” that I  
call  
as testframework?experimentname – no name=value and encoding stuff to  
parse – and testframework has several forms that post back to itself  
using the same URL)
