Set a custom HTTP header that will be included when using the Switcher. It's occasionally useful to identify your testing traffic, either to bypass your CDN, or to have your testing traffic omitted from analytics.

  1. Open WonderProxy Switcher extension and click Settings, then Header from the side menu
  2. Ensure that the feature is toggled on, and you have added values to both required fields
  3. Make sure to save your changes

Domain Filters

Specify domains you’d like to include or exclude from proxied traffic. Exclusion domains are useful when you wish to access internal network resources (like a bug tracker) while using the proxy. Inclusion is useful when you wish to only route some traffic through the proxy (like your website) while skipping the proxy for all other traffic.

  1. Open WonderProxy Switcher extension and click Settings, then click the Domain Filters menu option.
  2. Toggle the feature on
  3. Select the Include domains or Exclude domains option
  4. List the domains you would like to filter, separated by commas (, *
  5. Save your changes

Warnings & Notices

Notice for Chrome users

This popup may appear at some point after installing this plugin. It's warning you (correctly) that configuring a proxy server means all the data in your browser will be sent through that proxy. In our case, that's what we want: to use a proxy server for GeoIP testing. You will need to select "Keep Changes" to continue using the WonderProxy Switcher.
