This is where proxy-url-file-3A-2F-2F-2F fits in. If a system is configured to write out its proxy routing rules as text for debugging, and that rule involves routing to a local file (like file:/// ), it might encode the entire string "proxy-url-file:///" for safety. However, it is crucial to understand that while a PAC file can determine if a request uses a proxy, it never actually uses a file:// URI as the proxy destination. The PAC function's return values—specifiers like "PROXY" or "DIRECT" —are not URIs in the standard sense. Therefore, a string like proxy-url-file-3A-2F-2F-2F is more likely a byproduct of generic string-parsing or error-logging mechanisms applied to a data set that contains a URI.

Given the deprecation of local PAC files, how should developers and IT administrators manage proxy settings today?

A proxy server acts as an intermediary between a client and a server. If a web application allows a user to input a URL, and the application fetches that URL using a backend proxy, an attacker might try to force that proxy to fetch a local file instead of an external website. What is SSRF?
