is NGINX what I need? persist HTTP requests unreliable connection

I have a raspberry pi receiving HTTP requests that I need to forward to a server on the Internet. If the Internet is down these requests should be persisted locally (preferably to hard disk) before being sent to the server when the internet is later available. A forum user on reddit suggested NGINX can do this, is this correct?

If so can someone point me to any configuration examples that might help?

Thanks for your time
