htaccess rewrite block - target specific directory (for PreRender.io caching)

Question

I would like to modify the below ModRewrite block to only be triggered when the URL starts like this: http(s)://my-website.com/n/ ....

The rewrite is used to send the (angular) page to PreRender for caching so search engines can index it. The whole angular portion of the site lives under /n/ so that is all I need to cache

<IfModule mod_proxy_http.c>
        RewriteCond %{HTTP_USER_AGENT} baiduspider|facebookexternalhit|twitterbot|rogerbot|linkedinbot|embedly|quora\ link\ preview|showyoubot|outbrain|pinterest|slackbot|vkShare|W3C_Validator [NC,OR]
        RewriteCond %{QUERY_STRING} _escaped_fragment_

        # Only proxy the request to Prerender if it's a request for HTML
        RewriteRule ^(?!.*?(\.js|\.css|\.xml|\.less|\.png|\.jpg|\.jpeg|\.gif|\.pdf|\.doc|\.txt|\.ico|\.rss|\.zip|\.mp3|\.rar|\.exe|\.wmv|\.doc|\.avi|\.ppt|\.mpg|\.mpeg|\.tif|\.wav|\.mov|\.psd|\.ai|\.xls|\.mp4|\.m4a|\.swf|\.dat|\.dmg|\.iso|\.flv|\.m4v|\.torrent))(index\.php)?(.*) http://service.prerender.io/%{REQUEST_SCHEME}://%{HTTP_HOST}/$3 [P,L]

Answer 1

I think you'd want to add:

RewriteCond %{REQUEST_URI} /n/

like:

RewriteCond %{HTTP_USER_AGENT} baiduspider|facebookexternalhit|twitterbot|rogerbot|linkedinbot|embedly|quora\ link\ preview|showyoubot|outbrain|pinterest|slackbot|vkShare|W3C_Validator [NC,OR]
RewriteCond %{QUERY_STRING} _escaped_fragment_
RewriteCond %{REQUEST_URI} /n/

# Only proxy the request to Prerender if it's a request for HTML
RewriteRule ^(?!.*?(\.js|\.css|\.xml|\.less|\.png|\.jpg|\.jpeg|\.gif|\.pdf|\.doc|\.txt|\.ico|\.rss|\.zip|\.mp3|\.rar|\.exe|\.wmv|\.doc|\.avi|\.ppt|\.mpg|\.mpeg|\.tif|\.wav|\.mov|\.psd|\.ai|\.xls|\.mp4|\.m4a|\.swf|\.dat|\.dmg|\.iso|\.flv|\.m4v|\.torrent))(index\.php)?(.*) http://service.prerender.io/%{REQUEST_SCHEME}://%{HTTP_HOST}/$3 [P,L]
