Re: Accessing POST Data More Than Once

Maybe I should detail our problem a little more.

Our complex custom templating system requires a file containing a class 
called Page. Depending on the particular configuration of a given page, 
Page can get initialized several times. Page has a method to fetch CGI 
parameters (calls @cgi.params.dup where @cgi has been initialized to 
CGI.new). The first time this method is called, things work. Subsequent 
calls don't work under Ubuntu 5.04/Ruby 1.8. They did under Debian 3.0 
and Ruby1.6.

I tried setting a class variable with cgi.params the first time Page is 
initialized. This didn't work because we're using mod_ruby and Apache2 
which caches code in memory between requests.

Any ideas on a work-around (other than re-writing the template system)?
