Gateway Guardian Ad Blocker

Introduction

Gateway Guardian automatically prevents the display of many HTML-based Advertisements that are so prevalent on the World Wide Web today. This feature provides several key benefits including:

  • Increased Performance: Each ad that must be downloaded from a remote Ad Server requires a significant amount of additional processing overhead by the local computer. First, a DNS query is made to resolve the Ad Server name to it's associated IP Address. Second, one or more HTTP requests are made to the remote server to send the ad. And third, the incoming ad must be positioned and rendered onscreen.

  • Reduced Bandwidth Usage: In addition to the bandwidth used by the DNS queries and HTTP requests as mentioned above, the HTML Ad must also be downloaded to the local computer. HTML Ads are downloaded each time the ad is displayed on every computer on the local network and, often, these ads are animated graphical images which can be fairly large in size. All of this traffic significantly increases the amount of bandwidth used to display every web page containing popup or embedded HTML ads.

By blocking HTML Advertisements, your Internet connection performance will increase significantly and HTML pages will finish loading much faster than they ever did before. The improvements are easily noticeable no matter what type of Internet connection you are using - from an analog modem to high-speed broadband or even dedicated leased lines!

How it works

The Gateway Guardian Ad Blocker works by blocking access to the most common Ad Servers found on the Internet. (More than 600 as of Oct 18, 2002.) The web page requesting the HTML ad to be displayed simply cannot contact the Ad Server to download the specified ad and, instead, Gateway Guardian displays a plain-white "block" in the space where the ad was to be placed.

The Gateway Guardian Ad Blocker does not modify the HTML content in any way and, therefore, it cannot prevent some popup ad windows from appearing (they won't have any contents, however) or ads which are located on the same server that is hosting the web page being displayed (i.e. Yahoo! and Slashdot ).
