proxy_updatable

Details

• Type: boolean
• Default: false
• Example: {"proxy_updatable":true}

Every session's proxy / proxy_rules can be changed while it runs (see Proxies → live swap), with or without this flag: measured 2026-10-26 on Chromium and WebKit, a US exit moved to Germany on the next new connection. Older code that sends true keeps working.

Has no effect without a proxy.

Used in

• Case 68: CAPTCHA demo pages: what reCAPTCHA v3 scores and hCaptcha show seven browsers, and why a demo can't rank them
• Case 6: Swap a proxy mid-session without losing the login — and the keep-alive trap
