Propel Accelerator Webcelerate Edition is designed to provide
maximum acceleration for the Web sites you visit regularly.
So, the more you surf, the faster your favorite pages will
load!
Specifically, Propel Accelerator Webcelerate Edition speeds
up the delivery of Web pages four ways:
- Compression. Propel Accelerator Webcelerate Edition 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 Webcelerate Edition improves
upon your browser's caching ability. Webcelerate intelligently
retains and reuses Web pages
and page elements that have previously been sent to
your PC. That's why the longer Propel Accelerator Webcelerate
Edition is in use on your PC, the faster your Web pages
will
load.
- Persistent Connections. Propel Accelerator Webcelerate
Edition 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 Webcelerate
Edition lets you block unsolicited content, such as pop-up
ads and in page ads, which
contributes to long wait times.
In addition Propel Accelerator Webcelerate Edition includes
an advanced Download Manager that will transparently accelerate
downloads of most file types, including
MP3s and executable files (see below for more information).
Most Web content will be accelerated significantly, but there are certain exceptions:
| All text - HTML, markup,
and javascript. |
| Most graphics & photos -
including JPEG, BMP, PNG, and GIF images. |
| Most banner ads - including
animated gif images and Macromedia Flash content. |
| All browser-based emails |
| All email -
Messages and file attachments sent and received by
SMTP, POP3, and IMAP e-mail applications such as Eudora,
Outlook
and Outlook
Express. |
| MP3 files, executables & other
files - when downloaded from within your browser
(depending on the quality of your connection). |
|
| Streaming media, and audio and video files |
| Secure pages, such as those used
for online banking and credit card forms and pages
accessed over VPN |
| Files downloaded outside your browser using ftp |
|
The following table shows the specific content types that
are accelerated:
| Content Type(s) |
Primary Use of Content Type |
| Text |
Words that appear on standard web pages, including
browser-based email. |
| HTML, CSS, markup, and javascript |
The computerized instructions that cause pages
to be displayed with a particular look and functionality,
such as tables and borders. |
| JPEG |
A very common format for images. JPEG's appear
on web pages and browser-based email. Depending on
the
level of graphics acceleration chosen, the quality
of the JPEG on a Web page sped up by Propel Accelerator
will be affected. |
| GIF |
GIF images are often used for web page graphic
elements such as buttons, as well as animated images.
GIF's appear in banner ads and browser-based email
as well. Propel Accelerator speeds up GIF's without
impacting quality (lossless compression). |
| BMP |
BMP images are commonly used for publishing screen
shots to the web. |
| PNG |
PNG images are often used for web page graphic
elements such as buttons and borders. Propel Accelerator
speeds up PNG's without impacting quality (lossless
compression). |
| Flash |
Flash images and animation are used in banner ads
for other images. |

The Propel Accelerator Webcelerate Edition also provides two
additional key features to help make using the Internet more
enjoyable.
The
Propel
Webcelerate client provides you with a pop-up ad blocker to
block pop-up and pop-under windows, and a download accelerator
that
will
transparently accelerate downloads of most file types, including
MP3s and executable files.
Propel Accelerator can block pop-up and pop-under windows that clutter your
screen and slow down your surfing. You'll hear a noise and/or see an icon each
time a pop-up has been blocked. It's easy to see a pop-up that was blocked,
to allow some pop-ups to always be shown and to turn the feature on and off.
Propel Accelerator can block most advertisements that appear on web pages.
When an ad is blocked, it is replaced with a light gray box on the web page,
to make sure that web pages maintain their intended design. You can easily
view blocked ads by right clicking on the gray box. As with pop-up blocking,
you can turn this feature on and off any time you like.
Propel Accelerator will transparently accelerate downloads of most file types,
including MP3s and executable files.
Propel Accelerator Webcelerate Edition speeds up file downloads
in three ways - by checking for file mirror sites, by segmenting
files
for parallel downloading if possible, and by retaining partially
loaded file data across dropped connections. These are
the
same basic download acceleration techniques used by standalone
download management utilities.
If a user's connection is dropped during a long download,
when he or she reconnects and downloads the file again, Propel
Accelerator will be able to make use of the previously downloaded
portion of the file, and only download the remainder, as needed,
provided that the user is downloading from servers that support
partial downloads.
