Description

ngx_hash_init convert all the keys in lower case, so when use ngx_hash_find it returns null.
Below is the code line in ngx_hash.c.

key = ngx_hash(key, ngx_tolower(data[i]));

I think, you can make it generic which supports case sensitive keys.

yes, you are right, currently only lowercase keys are possible.
there is no great need in case sensitive keys though at the moment.

I think you should mention in the documentation that ngx_hash_t doesnt support case sensitive keys. And in my case it was needed and I just use another function to copy string instead of ngx_tolower. I hope it doesnt break the hash?
