Connections use a 'source port' at the client end and a 'destination
port' at the server end. These are agreed during the setup of the
connection, and last for its life (but there are oddities, like FTP,
which may use more than a single pair of ports).
Under normal circumstances the servers don't care which source port a
client uses, as long as it uses the correct destination port(s) for a
connection. The destination port will normally be port 80 for HTTP,
and port 443 for HTTPS.
Outgoing connections for HTTP generally use an epehemeral port
https://en.wikipedia.org/wiki/Ephemeral_port and the network stack software generally deals with all that for you.
It's completely transparent to the application using the connection.
It's an unusual question, is there a particular reason for posing it?
