Question on module user context

Server NGINX
1

Hi ,
If I set a context to a module with ngx_http_set_ctx(r, c, module)
Is this context valid only for current http request?
Should I set the context for each new http request?

BR,

Yes.

No, only for requests where you actually need context.

No, only for requests where you actually need context.

So the context is used for the scenario that the handler callback will
be
called multiple times to process the http request ?

Yes, it’s used to preserve some request-related state between
invocations of your module code.
