Headers

Manipulate HTTP request headers with Ferrum's headers. Headers apply to all subsequent HTTP requests, including assets, AJAX, etc. They are cleared at the end of every test.

headers = page.driver.browser.headers
headers.get # => {}
headers.set("User-Agent" => "Cuprite")
headers.add({ "Accept-Language" => "de" })
headers.get # => { "User-Agent" => "Cuprite", "Accept-Language" => "de" }

set overwrites already set headers, add merges into them. With permanent: false a Referer header is applied to the next navigation only:

page.driver.browser.headers.add({ "Referer" => "https://example.com" }, permanent: false)

page.driver.headers, headers=, add_headers and add_header are deprecated in favor of these.
