问题
I stupidly did a 301 redirect on websiteA.com to websiteB.com. After removing it from the .htaccess file the redirect is still in operation. I tried from outside the local network and it is still redirecting. I have cleared my cache and tried a different browser.
Does anybody have any suggestions?
UPDATE:
If I add a 302 redirect to this .htaccess file the site honours it. When I remove it, the old 301 redirect still happens.
.htaccess file for websiteA.com:
# -- concrete5 urls start --
Options -Indexes
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
# -- concrete5 urls end --
#RewriteCond %{HTTP_HOST} ^.*$
#RewriteRule ^/?$ "http\:\/\/www\.websiteB\.co\.uk\/" [R=301,L]
回答1:
The browser caches the 301 Moved Permanently, until told otherwise. It is default behavior: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.2.
To fix it in IE9:
- Open IE9 and press Ctrl+Shift+P for private browsing
- Navigate to the problem URL
- Then go back to normal browsing and all should be fine again

With Chrome, try to visit the website with Developers Console open (F12)
Make sure you have "Disable cache" checked under "Network" tab
This will bypass 301 redirect cache on browser-side.

The permanent redirect cache is probably in the browser
and in most browsers it is tricky to remove it.
But first, try using a different browser to see if this is the case.
In case the problem is in the browser:
This happened to me before and cleaning the browser data for that website was not enough.
I also realized that there is a trick for each browser.
In Safari (for Mac), I needed to select "Reset Safari..." (No panic, with this option neither bookmarks neither extensions are deleted).
I cannot recall how I did it for Chrome but was less traumatic.
The lesson
When playing with redirects use [302] first.
After everything was tested ok, change the code to [301]

Just delete the line about the Redirect.
And also everyone who has Google Chrome, do the following steps:
- Press CTRL + SHIFT + SUPR from your keyboard.
- Only check -> "Files and images stored in cache"
- Select in "Elements stored in cache since: Past week"
That will clear all your cache and you'll be fine.

I know this is an old post but i spent some time on the Web and my server to find the answer.
If you created an .htaccess file with a permanent redirection, the server will copy this redirection in the following file : "/var/.htaccess".
You have to edit this file to remove the redirection before cleaning the cache of your browser.
It worked on my Debian Jessie.

Try giving Apache a restart
(on Ubuntu servers: service apache restart or /etc/init.d/apache2 restart)
