Each body filter calls next filter in chain (till writer filter, 
which is special and writes data to a socket).

Most likely reason for "my filter isn't called" problems is 
registering a filter in a wrong place.  Make sure you do something 
like

HTTP_AUX_FILTER_MODULES="$HTTP_AUX_FILTER_MODULES \
                ngx_http_test_filter_module"

in your module "config" file.  Adding a filter to the HTTP_MODULES 
list won't do anything good.
