How to use forward proxy for HTTPS?

I have a use case where I have to put a middle server or relay or tunnel to do network communication with the following points:

I have a web server running, let say when I hit an API /request hosted my web server, it creates a post request to https://www.google.com and gives me a response through the endpoint.
I want a middle server (proxy etc.) which I will call while creating this post request instead of communicating through my webserver,
the call goes to the middle server and gives me the same response as I was getting directly.

Solution

For this, the SQUID proxy worked for me.

I came across NGINX, but we can not use NGINX as a forward proxy, also there are some observations that might be useful with this regard.

SQUID proxy also uses the conf file as similar to NGINX,
HTTPS traffic is encrypted, the proxy server need to do some more work to get something with Https requests,
For intercepting, and creating ACL rules, someone will need to have a dummy certificate to be used by the server to act as the owner of the requested content through the proxy,
a list of rules can be incorporated within SQUID.conf to achieve the filtering.

I hope this could be useful to achieve something like this.
