Buffers Chain

[Paulo Silva]

there is other option than modify the auto/modules file?

According to my goal (capture the full request response body) I would
say that my module must run right before the postpone.
Am I supposed to modify the auto/modules like follows?

if [ $HTTP_POSTPONE = YES ]; then
    HTTP_FILTER_MODULES="$HTTP_FILTER_MODULES $HTTP_POSTPONE_FILTER_MODULE"
    HTTP_SRCS="$HTTP_SRCS $HTTP_POSTPONE_FILTER_SRCS"
fi

# insert my module here!

if [ $HTTP_SSI = YES ]; then
    have=NGX_HTTP_SSI . auto/have
    HTTP_FILTER_MODULES="$HTTP_FILTER_MODULES $HTTP_SSI_FILTER_MODULE"
    HTTP_DEPS="$HTTP_DEPS $HTTP_SSI_DEPS"
    HTTP_SRCS="$HTTP_SRCS $HTTP_SSI_SRCS"
fi


I did check my modules config file and I did realize that it is
"queued" as HTTP_AUX_FILTER_MODULES. There are different queues for
core modules and addons?


May thanks for your time.
A definitive guide to nginx (modules) development would be a best-seller ;)
