Hi guys, I made a small HTTP Server Application. But I would like to
understand how to use the https protocol. The final project must run
on a linux server. Thank you, attached my sample program to change to
use https

Currently you must use a reverse proxy that already implements HTTPS.
Server side of fcl-web doesn't support it yet.

Other alternatives? Other components, perhaps from third parties, who
have examples to do what I want? We accept advice.

Indy (which is available in Lazarus' OPM) is cross-platform and works
on Linux.  Among many components, it has a TIdHTTPServer component
which supports SSL/TLS connections for handling HTTPS.

- Assign a TIdServerIOHandlerSSLBase-derived component (such as
TIdServerIOHandlerSSLOpenSSL) to the TIdHTTPServer.IOHandler property,
and configure it as desired (enabled SSL/TLS versions, certificates,
etc).

- Configure the TIdHTTPServer.Bindings property with the desired local
IP:Port pair(s) that you want to accept connections on.  For HTTP, you
should have a Binding on port 80, and for HTTPS, you should have a
Binding on port 443.  Though you can use any port(s) you want (in
which case URLs to your server will have to specify those ports
explicitly).

- If you use an SSL port other than 443, assign a handler to the
TIdHTTPServer.OnQuerySSLPort event, and have it return True or False
based on whether the provided APort parameter is a desired HTTPS port.

- Assign handlers to the TIdHTTPServer.OnCommand... events as needed,
such as OnCommandGet.

Personally I'd just put it behind an nginx proxy, pretty standard
setup for web deployments.
