Advise to develop a rights-control module

[Legrand Jérémie]

Thanks for your answers.

I studied the lua_module which is great but didn't feet my needs. My validation rule is quite complicated and could not be developed only with lua.
Just one comment about this module. Why it is not possible to use ngx.location.capture in set_by_lua directive ? It would be very helpful !

The static module is not called on access phase but is the first content phase handler registered in the nginx configuration (see auto/modules in nginx source). In my case, I could not set my module as the first content handler because it is not in the nginx core.

Finally, I achieved my goal by sending an ngx_http_send_response from my module and setting request keep_alive to 0. It works. Do you think this solution is ok ?

It should be possible. Look at how static module does it.
