Propel Accelerator + AdSubtract and Internet Explorer Like Propel Accelerator, AdSubtract uses a local proxy server. In order to use Proper Accelerator on a system running AdSubtract, some minor changes to preferences are needed.

The following steps allow you to "chain" Propel Accelerator and AdSubtract proxy settings together for use with Internet Explorer. Although there are a number of steps, each takes only a few moments to accomplish.

Configure Internet Explorer

Click on the Propel Icon and choose "options" then "advanced" and make sure that Propel is set to "only accelerate connections without proxy conflicts"

From Internet Explorer select Tools -> Internet Options--> click on the Connections tab.

Select the connection you are using (typically from the Dial-up settings list -- it may already be selected).

Click Settings...

Make sure that the "Use a proxy server for this connection" checkbox is checked. If not, do so.

Click the Advanced... button.

Make sure that the proxy address for HTTP is set to 127.0.0.1. If the proxy address is missing or is some other value, change it to 127.0.0.1 (AdSubtract may have automatically changed this setting at some point to "AdSubtract" -- that is fine.) Make sure that the port number is set to 4444, AdSubtract's default proxy server port number. If the port number is missing or different, change it to 4444.

Configuration Changes to AdSubtract

Double-click on the AdSubtract icon in the taskbar (near the system clock).

Click on the Proxy tab. Make sure that the checkbox "Use next-hop HTTP proxy server" is checked. If not, do so.

Set the HTTP Proxy to "localhost" (without quotation marks).

Set the port number to the Propel Accelerator proxy server port number. By default this number is 8080, but it may be different on your system.

Make sure that the checkbox "Use an AOL proxy" is not selected.

Click OK.

Verification

You can verify that both AdSubtract and Propel Accelerator are working together when:

The Propel Accelerator icon (blue propeller near the system clock) shows moving arrows when you browse the Internet.

The diagnostic test provided with AdSubtract succeeds. Double-click on the AdSubtract icon (yellow circle near system clock). From the Main menu click the Test Filtering button and follow the screen instructions. Re-Enabling AdSubtract After Stopping Propel Accelerator

Important: Propel Accelerator is run in the background at all times. If you stop or uninstall Propel Accelerator, you will get a message indicating that you need to change your Internet Explorer HTTP proxy setting. However, since the proxy setting is pointing to AdSubstract, you actually do not need to alter the browser settings. Instead, re-enable AdSubtract after stopping or uninstalling Propel Accelerator by following these steps:

Double-click on the AdSubtract icon (in the taskbar, near the system clock).

Select the Proxy tab.

De-select the "Use next-hop HTTP proxy server" checkbox.

Click Apply, then OK.

Verify using the diagnostic test provided with AdSubtract.

Double-click on the AdSubtract icon.

From the Main menu click the Test Filtering button and follow the screen instructions.
