.htaccess - redirect, if a specific url match - apache

Question

I need to redirect users to a new domain, but I need that in case a user visits a particular URL, then he/she needs to be redirected to another URL.
Let me clarify...
If the user visits http://oldexample.com/postvendita/ I need to redirect them to http://newexample.com/assistenza
Otherwise, for every other URL http://oldexample.com/* I need to redirect them to http://newexample.com/new-page
Here is my attempt:
Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteRule ^(.*)postvendita(.*)$ http://www.newexample.com/assistenza [L,R=301]
RewriteCond %{HTTP_HOST} !^oldexample\.com$ [NC]
RewriteRule ^(.*)$ http://www.newexample.com/new-page [R=301,L]
Now if I visit any of the old pages, I will be redirected to http://www.newexample.com/new-page, so the first rule doesn't work, how should I change it?

Answer 1

To handle this via .htaccess you'll want to match the first one and use a catch-all to redirect everything else:
RewriteEngine On
RewriteRule ^postvendita/?$ http://www.newexample.com/assistenza [R=301,L,NE]
RewriteRule .* http://www.newexample.com/new-page [R=301,L,NE]
A 301 redirect is a permanent redirect which passes between 90-99% of
link juice (ranking power) to the redirected page. 301 refers to the
HTTP status code for this type of redirect. In most instances, the 301
redirect is the best method for implementing redirects on a website.

Alternatively, if you're not comfortable writing RewriteRules, you can use the following lines:
Redirect 301 /postvendita/ http://www.newexample.com/assistenza
Redirect 301 /postvendita http://www.newexample.com/assistenza
Redirect 301 / http://www.newexample.com/new-page
Or with RedirectMatch:
RedirectMatch 301 /postvendita/? http://www.newexample.com/assistenza
RedirectMatch 301 .* http://www.newexample.com/new-page
