Question

I’m trying to redirect traffic, and I’ve managed to make it work on HTTP with this:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^wiki\.example\.com
RewriteCond %{HTTPS} !=on
RewriteRule (.*) http://example.com/wiki/$1 [L]
RewriteCond %{HTTP_HOST} ^db\.example\.com
RewriteCond %{HTTPS} !=on
RewriteRule (.*) http://example.com/db/$1 [L]

So far I haven’t gotten it to work with HTTPS. Anyone got any ideas?

You need to duplicate the code for HTTPS but set the RewriteCond to %{HTTPS} =on for the SSL redirect. I would also set the RewriteBase option as well as setting the R=301 flag on the redirect. Further you can simplify things a bit by using a back reference to the RewriteCond by using %N for wiki/db –

RewriteEngine On
RewriteBase /

# HTTP Redirects
RewriteCond %{HTTP_HOST} ^(wiki|db)\.example\.com
RewriteCond %{HTTPS} !=on
RewriteRule (.*) http://example.com/%1/$1 [R=301,L]

# HTTPS Redirects
RewriteCond %{HTTP_HOST} ^(wiki|db)\.example\.com
RewriteCond %{HTTPS} =on
RewriteRule (.*) https://example.com/%1/$1 [R=301,L]

If your domain name might change in the future and you want to make sure you are redirecting based on the match, you can also use more back references in your RewriteCond –

# HTTPS Redirects
RewriteCond %{HTTP_HOST} ^(wiki|db)\.(example\.com)
RewriteCond %{HTTPS} =on
RewriteRule (.*) https://%2/%1/$1 [R=301,L]
