Forwarder Pac Eval #
Usage: forwarder pac eval --pac <file|url> [flags] <url>...
Evaluate a PAC file for given URL (or URLs). The output is a list of proxy strings, one per URL. The PAC file can be specified as a file path or URL with scheme “file”, “http” or “https”. The PAC file must contain FindProxyForURL or FindProxyForURLEx and must be valid. Alerts are written to stderr.
Note: You can also specify the options as YAML, JSON or TOML file using --config-file
flag.
You can generate a config file by running forwarder pac eval config-file
command.
