Hi all,

I’m trying to get SWFupload to work in Rails 2. Since flash does not  
send cookies (containing session\_id) to rails, my session id is sent  
as a post parameter. I tried to override CGI::Session’s initialize  
method and grab the session id from the post parameter, but  
cgiwrapper.env\_table[‘RAW\_POST\_DATA’] always returns nil. Is there  
another way to get the raw post data inside CGI::Session’s initialize  
method?

Thanks!
