How does Propel work? (Article 1011)

Body

Propel Accelerator speeds up the delivery and presentation of web pages using a combination of compression and caching of text and graphics data, both at the PC and through the Propel Network. The result is a dramatic improvement in performance when you browse the web over a low-speed Internet connection. The benefits are especially pronounced when you are viewing dynamic HTML pages, such as are used by the most popular web sites.

Propel Accelerator uses four methods of acceleration:

  • Compression:
    Propel Accelerator delivers text and graphics more efficiently, using a proprietary compression technology that significantly reduces the size of web pages and page elements sent to your browser.
  • Caching:
    Propel Accelerator improves upon your browser's caching ability. Propel intelligently retains and reuses web pages and page elements that have previously been sent to your PC. That's why the longer Propel Accelerator is in use on your PC, the faster your web pages will load.
  • Persistent Connections:
    Propel Accelerator uses proprietary techniques to carefully manage and optimize the communication between your modem and our network of servers through a persistent connection. This eliminates the time wasted re-establishing and closing TCP/IP connections.

  • Optional Content Filtering:
    Propel Accelerator lets you block unsolicited content, such as pop-up ads and in-page ads, which contribute to long wait times.
