How to replace http with https in the URL for a domain and subdomains on it using a regular expression?

I'm looking through http://(([^.]+)\.)?livejournal\.com/

And what should I use to change only https at the beginning in the found URLs and leave everything else unchanged?

Example: found anhar.livejournal.com/3205896.html - received https://anhar.livejournal.com/3205896.html

Answer 1

Find: http://(([^.]+\.)?livejournal\.com/)
Replace:https://$1

Answer 2

From a cannon to sparrows. Why regular?
It's easier to use replace('http://', ​​'https://')
