Question

I have a URL like

www.testwebsite.com?param1=abc
or
www.testwebsite.com/?param1=abc

I need to redirect to

http://www.testwebsite.com/level1/xyz.html?customparam=123&param1=abc

I tried working on rewrite url but i am still new to this and need some help to achieve the solution

This is what i did till now

RewriteCond %{QUERY_STRING} param1=(.+) 
RewriteRule ^/$ /level1/xyz.html?customparam=123&param1=%1 [R=301,L]

Answer 1

Try adding the following to the .htaccess file in the root directory of your site.

Only param1 will be captured and passed through, other query string params will be dropped.

RewriteEngine on
RewriteBase / 

#if the param1 parameter is present
RewriteCond %{QUERY_STRING} (^|&)(param1=([^&]+))(&|$) [NC] 
#redirect
RewriteRule ^$ level1/xyz.html?customparam=123&%2 [L,R=301]
