Dear Users,

I’m reading through the docs and I’ve found that the rewrite module has  
some basic comparison operators. Is there a way or trick to implement  
some  
conditional processing at other parts of the configuration? My situation  
is that I’m serving a lot of files through nginx and I would like to be  
able to log the request if the file is bigger than a given size. I was  
thinking about using the $body\_size to log the actual size but I cannot  
implement the condition checking with the tools I know. Is there a way  
to  
achieve this with the current features of nginx?

Best regards,  
Mate
