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
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
achieve this with the current features of nginx?
