Could RAW_POST_DATA be altered?

Rails
1

I’ve been working on a very low-level issue on RubyAMF.

In a nutshell, I need to figure out if its at all possible that rails’
request.env[‘RAW_POST_DATA’] or request.raw_post for that matter could
possibly be interpretting a byte stream and mistakingly truncating it by
a byte or two in certain places.

For example, in this byte stream lies a compressing Gzipped stream. And
sometimes (like 1 in 100) this stream will be short a couple of
characters (like 1-3) and appear corrupted.

How can I access the raw data before ruby/rails puts its hands on it.
Anyway to dip into the CGI directly. I want as few operations on the
RAW_POST_DATA as possible.

There’s a thing where (to work around a bug in safari) the last byte
of a post request is dropped if it is 0
(see clean_up_ajax_request_body in action_controller/request.rb)
