Request fingerprinting parameters

The request fingerprinter class of scrapy-zyte-api generates request fingerprints for Zyte API requests based on the following Zyte API parameters:

• url (canonicalized)

  For URLs that include a URL fragment, like https://example.com#foo, URL canonicalization keeps the URL fragment if browserHtml or screenshot are enabled, or if extractFrom is set to browserHtml.

• Request attribute parameters (httpRequestBody, httpRequestText, httpRequestMethod), except headers

  Equivalent httpRequestBody and httpRequestText values generate the same signature.

• Output parameters (browserHtml, httpResponseBody, httpResponseHeaders, responseCookies, screenshot, and automatic extraction outputs like product)

• Rendering option parameters (actions, device, javascript, screenshotOptions, viewport, and automatic extraction options like productOptions)

• geolocation

• echoData

The following Zyte API parameters are not taken into account for request fingerprinting:

• Request header parameters (customHttpRequestHeaders, requestHeaders)

• Request cookie parameters (cookieManagement, requestCookies)

• Session handling parameters (sessionContext, sessionContextParameters)

• jobId

• Experimental parameters (experimental.*)
