I have a question regarding a Headless Browser for Classic ASP.

My company needs to have a website crawled by Google's crawler, but because the website is constructed dynamically by JSON script we need a Headless Browser to generate HTML snapshots.

I already searched around but can only find htmlunit, which seems to be for PhP only, or Xbrowser but that is for .Net sites.

Am I misinformed and can I use either of those? Or is there another option to create Html snapshots?
