Thanks a lot for all the help you are doing ! Also I have noticed that many sites  tell about specific ports typically 80 and 443 for proxy list ... Is it necessary ?
Thanks a lot
Apologies for the trouble !

No need to apologize, It's my pleasure to be of assistance.

I'm not sure why they'd be referring to port numbers to obtain proxy lists, particularly Port 80- this Is the main protocol for HTTP communications between the client and the web server.

As for port 443, It's primarily used for secure HTTPS traffic. In answer to your question. both ports are open to exchange secure & Insecure traffic, so there's no need to address them when grabbing/scrapping proxy lists.
