.htaccess redirect non existing pages based on index.php page with wildcard and something after it to index.php

问题

Please help, some website is arbitrarily adding dynamic query strings to my home page.

For example my home page is www.mysite.com/index.php and they link to many links like this:

www.mysite.com/index.php?a=something-something-something
www.mysite.com/index.php?a=something-other
www.mysite.com/index.php?a=some-other-thing

And those links are opening on my site, content of page are the same for every page, just like my original www.mysite.com/index.php

There are few hundreds of that links pointing to my site. So how I can redirect this:

www.mysite.com/index.php?a=something-something-something
www.mysite.com/index.php?a=something-other
www.mysite.com/index.php?a=some-other-thing
...

www.mysite.com/index.php or just to www.mysite.com/

This what I tried so far in my .htaccess file

RedirectMatch 302 ^index.php?a= http://www.www.example-ste.com/
RewriteRule ^/index.php?a=(.*) http://www.example-ste.com/

But still pages are opening on site.

How to redirect pages ending with "?pagewanted=all" to the same page but with out that "?pagewanted=all"

For example I need to redirect page:

www.mysite.com/something-something/something.html?pagewanted=all

www.mysite.com/something-something/something.html

Hello.

I just noticed something. I needed URL redirection rule which will redirect pages like:

www.mysite.com/index.php?a=something-something-something
www.mysite.com/index.php?a=something-other
www.mysite.com/index.php?a=some-other-thing

to home page of site, root. And you gave me this code:

RewriteEngine On
RewriteBase /

#if the query string has an a parameter
RewriteCond %{QUERY_STRING} (^|&)a= [NC]
#Redirect and remove query string parameters
RewriteRule .*  http://www.mysite.com/? [R=301,L]

And I must say it works fine, it does that, but I just noticed that it somehow blocks or redirect all links containing ?a= for example on some temporary pages I have links like:

i.php?a=something-something-something

So, can you adopt code just for pages based on index.php like:

www.mysite.com/index.php?a=something-something-something

and not for links with:

i.php?a=something-something-something

If I am right it works on all links with "a=" but I need just for "index.php?a="

Try adding the folloginw to the top of your .htaccess file

RewriteEngine On
RewriteBase /

#if the query string has an a parameter
RewriteCond %{QUERY_STRING} (^|&)a= [NC]
#Redirect and remove query string parameters
RewriteRule .*  http://www.mysite.com/? [R=301,L]

#if the query string has a pagewanted parameter
RewriteCond %{QUERY_STRING} (^|&)pagewanted=all [NC]
#Redirect and remove query string parameters for html pages
RewriteRule (.+\.html)  http://www.mysite.com/$1? [R=301,L]

Edit. Added rule to remove pagewanted=all
