Apache Mod_rewrite implements HTTP and HTTPS redirect jumps _linux

After your site has used HTTPS, you may want to redirect all HTTP requests (that is, port 80 requests) to HTTPS (that is, port 443). You can do this in the following ways: (Apache mod_rewrite)

<ifmodule mod_rewrite.c>
 rewriteengine on
 rewritebase/
 rewritecond%{server_port}
 Rewriterule ^ (. *) $ https://jb51.net/$1 [r=301,l]
</IfModule>

Put this code in the. htaccess file to enable redirection of HTTP to HTTPS.

And when you want to use the HTTP back, the reverse is OK:

<ifmodule mod_rewrite.c>
 rewriteengine on
 rewritebase/
 rewritecond%{server_port} 443
 Rewriterule ^ (. *) $ http://jb51.net/$1 [r=301,l]
</IfModule>

Where r=301 says moved permanently, which tells search engines or browsers to go directly to the latter's address, can use r=302 (Found) If it is only experimentally redirected.
