Allow certain files on the ignored extension list to be prerendered

[gsdriver]

It would be useful if I could override the extension to ignore list with certain files that I would like to retrieve such as sitemap.xml or favicon.icon. Perhaps an “allowableExtension” array of files or patterns?

Is there a reason you would want those requests to be sent to Prerender.io? The reason for the extensionsToIgnore is so that you can serve any static files directly from your server. The Prerender server should only receive a request for a URL that returns HTML. In your example, the sitemap.xml should be served from your server and not through the Prerender server.

Files like my sitemap.xml do live on my server, however I've set up nginx to forward bot requests to my Prerender server. I can look through the extensions within nginx to re-direct them, but it seems cleaner for me to handle that all in Prerender.io.
