Description
it looks like you missed check for
r->method == NGX_HTTP_GET
in
ngx_http_upstream_process_request(ngx_http_request_t *r)
so, if fastcgi_store directive is used, empty file will be stored on HEAD request

Thanks for the explanation!
Can you please explicitly describe this behavior in the official documentation ?
At the moment, the only information about this case is "no, it won't be cached, just proxied", which is differs from current state.
Note:
See TracTickets
for help on using tickets.
The method can be redefined using proxy_method directive in case of proxy, or using appropriate fastcgi_param in case fastcgi. If the Content-Length header is present in a response, it's used to check if the response is complete. In case it may not be known on some responses, it's a good idea to explicitly define method used in backend requests. Alternatively, use proxy_cache/fastcgi_cache, which will do method mungling by itself, as well as many other things.
