Hi guys, i’m new to this forum (already introduced myself ^^).

I’m writing a nginx handler module and i need to load a file in a server  
directive inside the config, let’s assume it’s something like:

server {  
…  
mymodule-ruleset /etc/nginx/mymodule-rules.json;  
…  
}

So i have a server structure like:

typedef struct {  
…  
ngx\_str\_t ruleset;  
…  
}  
ngx\_mymodule\_srv\_conf\_t;

I initialize the ruleset attribute inside the merge\_srv\_conf handler:

ngx\_conf\_merge\_str\_value( conf-\>ruleset\_path, prev-\>ruleset\_path,  
DEFAULT\_RULESET\_PATH );

( Where DEFAULT\_RULESET\_PATH is a constant #defined my me ).

The problem is, i have to load this file only once for server directive,  
but the user could ignore the mymodule-ruleset using its default value,  
so i can’t use an handler to load it (it could be never called).

Where’s the best place to load this file? In the postconfiguration  
handler ? If so, how do i retrieve the srv\_conf\_t inside the  
postconfiguration handler ?

Thanks for your time, i’m new to nginx developing and i’m finding some  
trouble to understand its structure.

PS: I’ve already read the guides specified in the wiki, but there’s  
nothing so specific.

See nginx-devel@ for the reply. Cross-posting isn’t really good  
idea.

I guess i’m gonna load it as a main configuration inside the post  
configuration handler, thanks so much 🙂
