Teleport VLX is also an enhanced capability webspider, having exploration, filtering, and rewriting capabilities that Teleport Pro lacks. Its enhanced abilities allow you to:
Use regular expressions to specify included as well as excluded areas to crawl
Specify domain aliases for crawling servers with multiple names
Borrow the browser's cookie cache, letting you perform complex authentication with your browser, and then crawl with Teleport
Inject custom HTTP headers into server requests
Synchronize your offline copy so that old files and orphans are automatically removed
Control HTML markup and inject meta tags with original URL and retrieval date/time stamps
Use customizable messages when rewriting links to unretrieved files

In addition, Teleport VLX is now able to crawl HTTPS (secure server) sites.

Teleport VLX requires a lot of memory to run efficiently. We recommend that your machine have 128Mb free memory for every 1 million addresses scanned. Machines with enough RAM will run Teleport VLX at its maximum speed and efficiency. The program can, however, run with less RAM -- it will just run more slowly.
