Use Google Web Designer with a proxy server

Google Web Designer's shell application supports the same custom proxy settings that the Chrome browser does. Learn more about Chrome and Chromium settings.

If you've already changed Chrome's settings to allow it to work with your proxy server, the changes for Web Designer should be familiar. If you're not sure what settings to use, contact your network administrator.

1. Locate Google Web Designer's application preferences

The location of Web Designer's application preferences depends on your operating system:

  1. Open the registry editor. From the Windows Start menu, click Run, then enter regedit in the Run dialogue.
  2. Navigate to the following registry key:
    HKEY_CURRENT_USER\Software\Google\Web Designer\Settings
  3. Add each proxy setting as a new value in the right pane by right-clicking the above registry key. For Boolean-type settings, use 32-bit DWORD values with 0 indicating false and non-zero values indicating true.

You can either use a text editor to edit the XML file containing Web Designer application preferences, or run commands in Terminal.

To use a text editor:

  1. Open the following .plist file:
  2. Add each proxy setting in XML format.

To use Terminal, run the following command for each setting that you want to change:

defaults write <setting-name> -<type> <value>

  1. Open the following configuration file in a text editor:
  2. If there's no Settings section, create one by typing [Settings] on a new line.
  3. Add each proxy setting on a new line in the Settings section.
