PAC File Generator (PROXY / HTTPS)

Generate and import PAC files. Supports proxy schemes like PROXY and HTTPS, domain/wildcards, and IP/CIDR.

Filename (no extension)

Scheme

Proxy host (FQDN or IP)

Port

Allow DIRECT fallback if proxy unreachable

Add multiple proxies for failover. They’ll be tried left-to-right.

Understands: var PROXY = "...", return "HTTPS ...; DIRECT", and bypass lists (DIRECT rules then unconditional proxy).

Mode (controls which boxes are used)

Proxy only inclusions (default DIRECT) Proxy all except exceptions (bypass list) Proxy everything (ignore inclusions & exceptions)

Tip: *.example.com matches subdomains only. To include apex + subdomains, use example.com (recommended) or include both.

Proxy inclusions (one per line)

Each line is a host pattern (exact or wildcard) or an IP/CIDR. Example: example.com covers example.com + subdomains.

Exceptions (bypass) — one per line

Exceptions are evaluated first. Wildcards are evaluated with shExpMatch(host, "pattern").

Generated PAC content

Host the PAC on a webserver or use a local file URL depending on your platform.

Notes: IP/CIDR matching uses dnsResolve() + isInNet() which can be restricted in some PAC runtimes. Prefer host-based rules where possible.
