upstream module / need to check pipe field

[David CARLIER]

Hi,

I was wondering if it might be better to check if pipe field before
attempting to clear the temp file ? Anyway it is checked as well line
4015 and below ... in this case u->pipe checks is sufficient
u->pipe->temp_file is checked inside ngx_http_file_cache_free
function.

Hope it helps.

Regards.
