This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Separates the output text from curl into an array of HTTP responses and the final response body (i.e. content). Response hashes contain the :status_code, :status_text and :headers.

Parameters:

output (String) —
The output text from curl containing HTTP responses, body content, or both.
max_iterations (Integer) (defaults to: 25) —
The maximum number of iterations for the while loop that parses HTTP response text. This should correspond to the maximum number of requests in the output. If curl's --max-redirs option is used, max_iterations should be max-redirs + 1, to account for any final response after the redirections.

Returns:

(Hash{Symbol => T.untyped}) —
A hash containing an array of response hashes and the body content, if found.

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Check if a URL is protected by CloudFlare (e.g. badlion.net and jaxx.io).

Parameters:

response (Hash{Symbol => T.untyped}) —
A response hash from #parse_curl_response.

Returns:

(Boolean) —
Whether a response contains headers indicating that the URL is protected by Cloudflare.

.url_protected_by_incapsula?(response) ⇒ `Boolean`

This method is part of a private API. This method may only be used in the Homebrew/brew repository. Third parties should avoid using this method if possible, as it may be removed or changed without warning.

Check if a URL is protected by Incapsula (e.g. corsair.com).

Parameters:

response (Hash{Symbol => T.untyped}) —
A response hash from #parse_curl_response.

Returns:

(Boolean) —
Whether a response contains headers indicating that the URL is protected by Incapsula.

  set_cookie_header.compact.any? { |cookie| cookie.match?(/^(visid_incap|incap_ses)_/i) }
