How to capture the requested url and pass its substring to some other link in .htaccess – Apache

I am making some changes in .htacess file and i want to capture the requested url, create substring of it and pass it to third part url.
For example

I am working on ubuntu, so currently my .htaccess file is in folder test. So when i access localhost/test/http://www.facebook.com , it takes me to service.prerender.io/test/http://www.facebook.com but i want to eliminate the ‘test’ and forwrd the request like service.prerender.io/http://www.facebook.com

Here is the code of my .htaccess file

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/script.php
RewriteRule ^(.*)$ http://service.prerender.io%{REQUEST_URI} [L,QSA]
</IfModule>

    You can use the RewriteCond %{REQUEST_URI} to set capture groups and instead of rewriting to http://service.prerender.io%{REQUEST_URI} you can rewrite to something like this http://service.prerender.io/%1.

    Here is an example (untested):

    <IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/script.php
RewriteCond %{REQUEST_URI} ^/?test/([.]+) [NC]
RewriteRule ^(.*)$ http://service.prerender.io/%1? [L,QSA]
</IfModule>

    What you are trying to captures is not directly the requested uri but part of it. You can get it from rewrite rule

    Try following

    RewriteRule ^test/(.*)$ http://service.prerender.io/$1? [L,QSA]

    If you’re accessing a page something like,

    https://www.example.com/thisdir/thisfile.php

    Then you will get following as request uri and script uri

    REQUEST_URI: /thisdir/thisfile.php

SCRIPT_URI: https://www.example.com/thisdir/thisfile.php

    And https://github.com/prerender/prerender-apache is more information about htaccess and prerender
