You're looking for http://search.cpan.org/~flora/Catalyst- 
Runtime-5.80007/lib/Catalyst.pm#ON-DEMAND_PARSER

Set that, and the body of the request will only be read when you  
access it. So you can check the content-length (and other headers)  
and reject the request before the rest of the content arrives...
