Hi guys,

I am using nginx and I have a FastCGI server(python, using flup library)  
program to accept file upload request from browser. One problem I  
encounter  
is when the file is large, like exceeds 1MB, my python fastcgi program  
will  
not receive any data, but when the file is smaller, it just works fine.  
I am  
not sure how nginx work with fastcgi module, does it have limitations on  
file size? Is it possible to tune it?

Thanks.  
Bin
