When ProxySG policy includes rules that invoke CAPTCHA validation for client requests for uncategorized URLs, some web pages can't load content from third-party domains. For example, some images links are broken, web page formatting is missing, or users cannot interact with certain web page elements.
Note: CAPTCHA policy was introduced in SGOS 6.6.4. Refer to the
SGOS Administration Guide and the
Content Policy Language Reference for details.
If you write CAPTCHA policy for URLs that link to inline content from uncategorized third-party domains, use
validate.mode(form-cookie-redirect). Otherwise, the default
form-cookie mode is used. Refer to the following example:
; for URLs where the content filter cannot determine the category, ; use specified validator and form-cookie-redirect auth mode <Proxy> category=unavailable validate(CAPTCHA_1) validate.mode(form-cookie-redirect)
