Help with htaccess

Hi everybody.,

I'm new here and I need your help.

I have 4 Joomla websites, 1 on my main domain and 3 on subdomains. I need to redirect all requests to https except the requests to the subdomains.

For example:
domain should be redirected to HTTPS
blog domain should not be redirected to HTTPS

Thank you!






I didn't find the right solution from the internet.

'Tis not a Joomla problem. Use Google to search for .htaccess issues.
