Regarding the custom header in cy.visit() and cy.request() as 'Accept-Language'

[mayankrajjaiswal]

Hello,

I want to add a custom header while calling visit() as per the documentation I added the header 'Accept-Language', but the document says that the header will be sent only once.

As per the document: https://docs.cypress.io/api/commands/visit#Arguments

I tried adding the header in three ways as below.

Ex 1:
cy.visit('/', {
headers: {
'Accept-Language': 'fr',
},
});

Ex 2:
cy.visit('/');
cy.request({
url: '/',
headers: {
'Accept-Language': 'fr',
},
});

Ex 3:
cy.visit('/', {
onBeforeLoad(win) {
Object.defineProperty(win.navigator, 'language', {
value: 'fr',
});
},
});

Question: Cypress sends the request to the server then that server actually sends the request for the locale pages to the other server so the 'Accept-Language' header is required throughout the subsequent requests.
Is there any way this can be done by cypress so that the 'Accept-Language' header is attached to all the requests?
I also tried it via cy.request(), but that also did not work.

Mayank
