CodeIgniter htaccess modification for semi https and without www version

.htaccess, apache, codeigniter, php

Solution

It is easier to handle the no-www and toggle-protocol redirects separately. In the following example:

- The www requests are redirected to no-www as-is (handle toggle-protocol redirect on next request)

- The http requests for selected pages are redirected to https version

- The https requests for other pages are redirected to http version

Note the leading `/...(/|$)` in the following examples. They ensure that complete path fragments are matched (e.g. in the third set of rules `/js/main.js` matches but `/jsmith/profile` does not).

RewriteEngine On

# Force NOWWW
RewriteCond %{HTTP_HOST} ^www\.(.+) [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [R=302,L]

# Force HTTPS
RewriteCond %{HTTPS} =off
RewriteCond %{REQUEST_URI} /(login|account_detail|alternate_address|update_password)(/|$)
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=302,L]

# Force HTTP
RewriteCond %{HTTPS} =on
RewriteCond %{REQUEST_URI} !/(login|account_detail|alternate_address|update_password|css|img|js)(/|$)
RewriteRule ^ http://%{HTTP_HOST}%{REQUEST_URI} [R=302,L]

# Hijack all requests
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [L]

The following tests passed:

http://www.example.com/
    http://example.com/

http://www.example.com/a/b?c=3&d=4
    http://example.com/a/b?c=3&d=4

http://www.example.com/login
    http://example.com/login
        https://example.com/login

https://www.example.com/js/javascript.js
    https://example.com/js/javascript.js
        http://example.com/js/javascript.js

Note: Remember to replace 302 with 301 after testing.

Problem

Rather than in core PHP, htaccess modification is different. So, after some searching I have reached to the following code. before that, my requirements are standard in my project. - www is strictly not allowed in whole site. i.e. redirect directly to non-www version. - HTTPS is for some pages. (checkout, login page) . Strictly HTTP for other pages. - removing CodeIgniter's default index.php Here is my code. ``` RewriteEngine on ################################# # force HTTPS RewriteCond %{HTTPS} =off RewriteCond %{REQUEST_URI} (checkout|login) RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] # force HTTP RewriteCond %{HTTPS} =on #RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC] RewriteCond %{REQUEST_URI} !(checkout|login|css|img|js) RewriteRule .* http://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] # Strict to non-www version >>> Not Working RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC] RewriteRule ^(.*)$ http://%1%{REQUEST_URI}/$1 [R=301,NE,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php/$0 [L] ``` Issue: Not able to reach to result of non-www version of site update(17 Oct) ``` # Strict to non-www version. RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC] RewriteCond %{REQUEST_URI} (login|account_detail|alternate_address|update_password) RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L,QSA] RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC] RewriteCond %{REQUEST_URI} !(login|account_detail|alternate_address|update_password|https|css|img|js|resources|images) RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L,QSA] # force HTTPS RewriteCond %{HTTPS} =off RewriteCond %{REQUEST_URI} (login|account_detail|alternate_address|update_password) RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] # force HTTP RewriteCond %{HTTPS} =on RewriteCond %{REQUEST_URI} !(login|account_detail|alternate_address|update_password|https|css|img|js|resources|images) RewriteRule .* http://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php/$0 [L] ``` On this new updated code, htaccess tester site displaying everything perfectly. But, after updating to site there are many issues. When I open this link ``` https://example.com/login ``` It keeps looping, not stopping. And on this link http://www.example.com/login it redirects to ``` https://login/login ```
