RedirectMatch 301 remove query string / URL Parameters-CodePudding

i need a Solution for the google search console error links and RedirectMatch 301 remove query string / URL Parameters in my htaccess:

Google Search Console Links:

https://www.domain.de/?main_page=index&zenid=umf5etlrmr4blnuiq0e4jsp6l2&cPath=15_326&sort=20a&alpha_filter_id=68

https://www.domain.de/index.php?main_page=product_reviews_write&products_id=9985&cPath=5_380&number_of_uploads=0

https://www.domain.de/?main_page=index&cPath=46_47&sort=20a&alpha_filter_id=70

https://www.domain.de/?currency=USD&main_page=products_new&disp_order=7&page=141

https://www.domain.de/?main_page=index&zenid=mj6nsb9r53goiu6e13nb80tfq7&cPath=1_160&sort=20a&alpha_filter_id=70

https://www.domain.de/?currency=USD&main_page=index&cPath=3_137

https://www.domain.de/?main_page=index&cPath=46_76&sort=20a&alpha_filter_id=84

https://www.domain.de/?main_page=index&cPath=5_6&sort=20a&alpha_filter_id=85

https://www.domain.de/index.php?main_page=index

And many more.

I test this way in the htaccess, but it didn't work:

RedirectMatch 301 ^/?main_page*$ https://www.domain.de/
RedirectMatch 301 ^/?main_page\=$ https://www.domain.de/

RewriteEngine on
RewriteCond %{QUERY_STRING} ^main_page$ [NC]
RewriteRule ^/?main_page?$ https://www.domain.de/ [L,R=301]

CodePudding user response：

You can use the following generic rule to remove query strings

RewriteEngine On


RewriteCond %{QUERY_STRING} ^(main_page|currency) [NC]
RewriteCond %{REQUEST_URI} ^/$ [OR]
RewriteCond %{REQUEST_URI} ^/index\.php$ [NC]
RewriteRule ^ %{REQUEST_URI}? [L,R=301]

CodePudding user response：

Adding one more approach of htaccess rules here, written as per shown samples. Using Apache's THE_REQUEST variable here.

Make sure to clear your browser cache before testing your URLs.

RewriteEngine ON
RewriteCond %{THE_REQUEST} \s/(?:index\.php)?/?(?:\?(?:main_page|currency))?\s [NC]
RewriteRule ^ %{REQUEST_URI}? [L,R=301]

OR as an alternative use following code(using QSD flag here to remove query string):

RewriteEngine ON
RewriteCond %{THE_REQUEST} \s/(?:index\.php)?/?(?:\?(?:main_page|currency))?\s [NC]
RewriteRule ^ %{REQUEST_URI} [L,R=301,QSD]
