Hello,

I am writing an nginx plugin and I am trying to send sub-requests to an  
upstream server.  
I am aware of the ngx\_http\_subrequest function but I didn’t succeed to  
use  
it in my case and I am not sure it is what I need.

In my use case, I have a structure in shared memory. This structure must  
leave as long as some conditions are fulfilled based on several  
sequential  
sub-requests to an upstream server. My first problem is that  
ngx\_http\_subrequest must have a server request to work. I would prefer  
to  
send a client request based on an internal event (in my case a timer  
event).  
If this is not possible, I can use a server request to do that but in  
that  
case I don’t want to add sub-requests responses content to the response  
body. Is this possible ? Do you have any advice ?

Thanks
