htacess重定向-更改URL的查询部分

Question

Google picked up the following URL and ranked it:

http://www.example.com/yyy/zzz-99.php?item_id=99&sort=1 (the item_id=99 part should not be there).

Since I picked up the error and fixed it, I have added the following line to my htaccess:

RedirectPermanent /yyy/zzz-99.php?item_id=99&sort=1 http://www.example.com/yyy/zzz-99.php?&sort=1

However that redirect does not work. Any clue on what i am doing wrong?

Answer 1

I think you need mod_rewrite to achieve even that single replacement, because includes a query string.

You may try this in the .htaccess file in root directory, provided mod_rewrite is enabled:

Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI}   ^/yyy/zzz-99\.php  [NC]
RewriteCond %{QUERY_STRING}  item_id=99&sort=1  [NC]
RewriteRule .*        /yyy/zzz-99.php?&sort=1?  [NC,L,R=301]

Redirects

http://www.example.com/yyy/zzz-99.php?item_id=99&sort=1 to

http://www.example.com/yyy/zzz-99.php?&sort=1

For silent mapping, remove R=301 from [NC,L,R=301].

Answer 2

Check the name of your .htaccess file. Make sure it starts with a period.

redirect 301 /index.html http://www.domain.com/index.html 
redirect permanent /index.html http://www.domain.com/index.html 
redirectpermanent /index.html http://www.domain.com/index.html

Answer 3

use 301 redirect in .htaccess:

Redirect 301 http://www.example.com/yyy/zzz-99.php?item_id=99&sort=1 http://www.example.com/yyy/zzz-99.php?sort=1

Redirect 301 (from) (to)
