.htaccess - “Too many redirects” when trying to fo

Question

I am trying to force a subfolder (/bbb/) of my root domain to show always as https. Also my .htaccess file take care of the extensions of the pages.

I have put the .htaccess file inside my /bbb/ folder but I get "Too many redirects" when I try to force to connect to https, without it everything works fine.

Whats wrong in my code?

Options +FollowSymLinks -MultiViews
Options +Indexes
AcceptPathInfo Off
RewriteEngine on
RewriteBase   /

ErrorDocument 404 https://example.co.uk/404page/404.html

#Force from http to https
RewriteCond %{SERVER_PORT} 80 
RewriteCond %{HTTP_HOST} !^bbb.example.co.uk/$
RewriteRule ^(.*)$ https://bbb.example.co.uk/$1 [R=301]

#take off index.html
 RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{REQUEST_URI} ^(.*/)index\.html$ [NC]
RewriteRule . http://www.%{HTTP_HOST}%1 [R=301,NE,L]

## hide .php extension
# To externally redirect /dir/foo.php to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R,L,NC]

## To internally redirect /dir/foo to /dir/foo.php
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_URI}.php [L]    

## hide .html extension
# To externally redirect /dir/foo.html to /dir/foo
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.html [NC]
RewriteRule ^ %1 [R,L,NC]

## To internally redirect /dir/foo to /dir/foo.html
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteRule ^ %{REQUEST_URI}.html [L]

Answer 1

Problem is in this rule:

#Force from http to https
RewriteCond %{SERVER_PORT} 80 
RewriteCond %{HTTP_HOST} !^bbb.example.co.uk/$
RewriteRule ^(.*)$ https://bbb.example.co.uk/$1 [R=301]

Change this rule to:

#Force from http to https
RewriteCond %{HTTPS} off 
RewriteCond %{HTTP_HOST} =bbb.example.co.uk
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301]

You have condition reversed due to use of ! at start and have an extra slash at end which will never be matched hence making your condition always return true.

Make sure to clear your browser cache before testing this.

try this:

RewriteEngine On
RewriteCond %{ENV:HTTPS} !on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Answer 3

If you have a proxied server or if you're using shared hosting then sometimes you'll get a free SSL via CloudFlare. And if you are using a framework like CodeIgniter or Laravel then you always have a route file. So sometimes the answer I have given above might not work.

In that case when you try to redirect to https you might get unlimited loops. So to resolve that you could try below:

RewriteEngine On

# If we receive a forwarded http request from a proxy...
RewriteCond %{HTTP:X-Forwarded-Proto} =http [OR]

# ...or just a plain old http request directly from the client
RewriteCond %{HTTP:X-Forwarded-Proto} =""
RewriteCond %{HTTPS} !=on

# Redirect to https version
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
