I asked this question in Stackoverflow but one of the respondents told me to ask it in here instead. I wonder if this is something that can be done in htaccess?

I have this URL:

https://www.example.com/folder/New.jsp?par=new1 

...which I want to redirect to:

 https://www.example.com/folder/New.jsp

how should I do that?

Basically I have par=new1|new2|new3|new4 that would like to be redirected to https://www.example.com/folder/New.jsp.

Any help from you will be very much appreciated.

If you just need the parameters taken off, it's pretty straight forward

RedirectMatch https://www.website.com/folder/New.jsp(?par=.[a-z]) https://www.website.com/folder/New.jsp

No mod_rewrite needed.

In order to match specific URL parameters, you need to use mod_rewrite with a condition that checks against the QUERY_STRING server variable. The mod_alias Redirect and RedirectMatch directives match against the URL-path only and can not be used to check the query string.

Try the following near the top of the .htaccess file in the document root:

RewriteEngine On

RewriteCond %QUERY_STRING ^par=(new1|new2|new3|new4) [NC]
RewriteRule ^folder/New.jsp$ /$0 [NC,QSD,R,L]

The QSD flag (requires Apache 2.4) on the RewriteRule directive discards the original query string from the redirected URL. If you are still on Apache 2.2 then use a ? at the end of the substitution string instead. For example: RewriteRule ^folder/New.jsp$ /$0? [NC,R,L].

$0 is a backreference to the entire URL-path that is matched by the RewriteRule pattern. ie. folder/New.jsp.

Note that this is a 302 (temporary) redirect. If a 301 (permanent) redirect is required then change the R flag to read R=301.
