Permanent structure to accumulate data

Unfortunately, the question is ambiguous. 

You can put it into the structure, you initialized `mycf =
ngx_pcalloc(cf->pool, size)`, 
where cf is `ngx_conf_t *cf`, if you want to save it per location.
Then you can get it in the handler, using `mycf =
ngx_http_get_module_loc_conf(r, ngx_http_your_module);`...

There are many another places, where you can put it. 
E. g. just as static variable like `static int var`, so valid per

But you should provide more info what exactly you want do.

For example another issue may be also multiple-workers at all (that are
processes, not the threads in nginx), so 
if it should be exactly one counter across all workers, then you should
put it into the shared memory (or somewhere in shared pools, using
ngx_slab_alloc functions). The good example would be own nginx module
Because otherwise, each worker will just get its own counter.
