Hi,
I’d like to put $content_length in proxy_cache_key in order nginx to check if file had changed and send it instead of old file if it’s case.
But the $content_length is always empty. Why ?
Or do you have another solution for my problem ?
Thanks,
Thibaut

Hi That’s a good idea but I think it’s not possible The key is set before request is sent to backend but it can only know the content length after the request is sent to backend (catch 22)
Ok, it’s what I supposed but I was not sure. Is there an alternative ?
