I am using zf2 and have apache installed on server. I have added the following lines in my .htaccess file.

RewriteEngine On 
<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|\.ttf|\.woff))(.*) http://service.prerender.io/%{REQUEST_SCHEME}://%{HTTP_HOST}/$2 [P,L]
</IfModule>

But still it is not redirecting my url to corresponding prerender url. Even I have changed the User Agent to google bot and added the escaped_fragment as query paramter. Am I testing correctly or there is something wrong with this htaccess code ?

Is there a way to have the page cached when a user visits a page? or should this be automatic and that I'm doing it wrong?

If you have prerender working and running for all pages except the root(home) page.
Your .htaccess might have the URL set to /index.php or /index.shtml for the homepage. If so, you could change your rewrite rule to this:

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|\.ttf|\.woff))(index\.php)?(.*) http://service.prerender.io/http://www.example.com$3 [P,L]

I added (index.php or index.shtml)? to capture that out if found and changed the $2 to $3. Don't forget to change the http://www.example.com to your domain.

A warning to anyone using vector files. You will need to add a |\.svg capture group to the proxy rule.

Hey all, I'm running into a problem when trying to Rewrite part of the URL being cached in prerender.io. I've tried removing that part of the URL using:
Rewrite ^root-directory/parent-directory/dist/(.*)$ $1 [R,L]
Doing this inside of:

<IfModule mod_proxy_http.c>
        Rewrite ^root-directory/parent-directory/dist/(.*)$ $1 [R,L]
        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|\.ttf|\.woff))(.*) http://service.prerender.io/https://www.example.com/$2 [P,L]
    </IfModule>

Doing this on the live server results in TOO_MANY_REDIRECTS. Is there anyway to solve this? I've changed the https://www.example.com/$2 to represent my sites URL

Just adding 2 cents:
On my hosting provider (Dreamhost), the [NC,OR] yielded strange results when just copy/pasting. On RewriteCond with only one line, I had to write it as
RewriteCond … googlebot|yandex|…|…|… [NC]
(re-writing the RewriteCond with one per line also worked, but not with [OR] on the first line. This would work:)

RewriteCond … googlebot [NC]
RewriteCond … yandex [NC,OR]
RewriteCond … WhatsApp [NC,OR]

note the seemingly missing OR on the first line

On the other hand, my second cent is that last WhatsApp entry - turns out WhatsApp does the scraping directly from inside the app (at least it did on my android phone today ;) So my full line is now
RewriteCond %{HTTP_USER_AGENT} googlebot|bingbot|yandex|baiduspider|facebookexternalhit|twitterbot|rogerbot|linkedinbot|embedly|quora\ link\ preview|showyoubot|outbrain|pinterest\/0\.|pinterestbot|slackbot|vkShare|W3C_Validator|WhatsApp [NC]
