[nginx module] Save response into temp file

[hungnguyen]

Hello, 

Sorry for my late replay. Now I can be able to write file into disk and read
from it without problem (csv file) by using this:
          ngx_temp_file_t *tf;
            tf = ngx_pcalloc(r->pool, sizeof (ngx_temp_file_t));
            tf->file.fd = NGX_INVALID_FILE;
            tf->file.log = nlog;
            tf->path = clcf->client_body_temp_path;
            tf->pool = r->pool;
            tf->persistent = 1;
            rc = ngx_create_temp_file(&tf->file, tf->path, tf->pool,
tf->persistent, tf->clean, tf->access);
            //ngx_write_chain_to_file(&tf->file, bucket->first,
bucket->content_length, r->pool);
            ngx_write_chain_to_temp_file(tf, bucket->first);

I set persistent to 1 and I can read from it. 
The problem is after reading file and processing it, I have to delete file
manually. 
How can file can be delete automatically just after sending nginx's chain to
next filter. 

Other question: I write chain into file in order to read from it again. is
it possible to use nginx's chain as a file buffer?
