Why we can't read stream during the access phase

[daxiong380380]

After I put a patch to nginx,I find that nginx can't read stream,can we do any thing to solve the problem

Try to read socket within content_by_lua* directive. Note that this directive can not coexist with proxy_pass.
I will take a look at this as long as I get some time. Also patches are welcome

@ryeyao I'm sorry to that ,I mean I can't read the stream during the access phase after patched nginx-allow_override_stream_access_handler.patch & nginx-init_session_before_access_handler.patch .

As you say, we can read socket within content_by_lua directive,but if I use the content* directive,I can't use proxy_pass.In my project,I plan to read and parse the socket,then I can choose the proxy address,so I can send the socket stream to the address that I have set.
I don't know whether there is some methods to achieve my aim.
Thank you .

Hi,
I plan to use the cosocket to the server during the content phase,so I shoud create tcp socket and connect it, when I create tcp socket during the content phase,I'd like to save this socket so that I can reuse it in the next requst,is this idea correctly?
or are there some other ways to reuse the socket in several request?

Correct (hopefully). (sorry for taking so long to reply..)

There should be several ways to achieve this (which I am not familiar with). You may ask openresty group for some help.
