Since HTTPS proxy does not support proxying DNS requests and Chrome does not support DNS over SOCKS protocol, all prefetched DNS requests will go through the system DNS. Now, the issue is that DNS Prefetching continues to function when pac_script mode is used. The highly dynamic nature of PAC scripts means the majority of VPN extensions use the mode pac_script over fixed_servers. For example, a VPN extension can use a PAC script that determines if a user is visiting Netflix by having a rule that compares the URL and assigns a proxy server that is optimized for streaming. Free plan provides 10 GB of data per month (if you confirm your email address), and the Pro plan has unlimited data and unlimited connections. In pac_script mode on the other hand, an extension provides a PAC script which allows dynamically changing the HTTPS/SOCKS proxy server’s host by various conditions. Windscribe is a VPN desktop application and VPN/proxy browser extension that work together to block ads, trackers, restore access to blocked content and help you safeguard your privacy online. In fixed_servers mode, an extension specifies the host of a HTTPS/SOCKS proxy server and later all connections will then go through the proxy server. I do not have admin rights on my work laptop.
