JavaScript enabled websites

While WebCopy will download JavaScript enabled websites and detect any linked JavaScript in HTML tags, by default it does not parse and execute JavaScript. JavaScript enabled-crawling can be enabled, but this has several caveats.

Downloading the raw source code for web sites

WebCopy does not download the raw source code of a web site, it can only download what the HTTP server returns. This means you cannot, for example, use WebCopy to download the PHP source code of a web site or any backend databases - unless that website is incredibly badly configured!

Caveat emptor

While WebCopy will do its best to create an offline copy of a website, advanced data driven websites may not work as expected once they have been copied as the underlying source code and databases for a website can never be downloaded unless expressly offered by website owners.
