Hello,

I am currently working on a nginx module, that parses user defined
strings for variables using ngx_http_complex_value_t. That works great
with all variables defined in ngx_http_variables.c (i.e.
$body_bytes_sent). However, variables as $bytes_sent do not exist here
since ngx_http_log_module uses its own variable parsing system. What
is the best way to use these extra variables in my module? I have
thought of the following options, I am not very sure about what is the
best way to go:
a) Copy the ngx_http_log_module code in my own module and rename every
single type and function to avoid double definitions. Reuse functions
and types from there.
b) Move the ngx_http_log_module code in my own module directory and
compile it only there. Reuse functions and types from there.
c) Write own variable parsing system, reuse a few snippets from
ngx_http_variables and ngx_http_log_module, whatever fits best.
d) Use complex values and try to extend the ngx_http_core_variables
array to include $body_bytes_sent and the other missing variables (I
don't understand why they are not included here anyway?).
e) Any better way to achieve that?

I'd really appreciate your help.

Regards
Benjamin
