I have a HTML page which references external stylesheets and shows some images. I'm looking for an easy way to include all referenced external resources in the HTML file directly, so that it doesn't have any external references any more. (Images should be included in the HTML file using the
<img src="data:image/jpg;base64,[...] method).
EDIT: I want to do this so that my web proxy can deliver a nice-looking error page if the backend is down, so I have to assume all my webservers cannot deliver the static content which would normally be linked to from my websites (CSS, images).
