How to redirect from HTTP to HTTPS with exceptions in htaccess?

Question

htaccess

Good day!
There is a code in htaccess:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
</IfModule>

You need to add links to the exclusions:

http://example.com/?wc1c=exchange
http://example.com/wc1c/exchange/

Tried like this, but throws on the main page:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} !on
RewriteCond  %{REQUEST_URI}  !^/wc1c/exchange/
RewriteCond  %{REQUEST_URI}  !^wc1c=exchange
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
</IfModule>

Can you please tell me how to write exceptions?

Answer 1

RewriteCond %{SERVER_PORT} !^443$
RewriteCond  %{REQUEST_URI}  !^/wc1c/exchange/& [NC]
RewriteCond %{QUERY_STRING} !(^|&)wc1c\=exchange($|&) 
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}? [L,R=301]
