I have saved a local copy of a financial web page (stock prices) that doesn't scrape very well. I assume it is because the content is changing too quickly. I'm unable to even create a sitemap to access this offline page. The following URLs are all rejected with the message "The start URL is not a valid URL", even though my browser accepts them all.
Url: file:///home/usr/file.html
Url: http://0.0.0.0:8000/Documents/file.html
Url: http://localhost/file.html
Sitemap:
{id:"sitemap code"}
