How is the culture set per circuit/session in Blazor server

Hi;

Sorry for a new question but my comment in this question does not appear (disappearing comments seems to be endemic on this site).

Very basic question. How does the culture get set for a session/circuit in Blazor server. In the case of no prompt to the user allowing a change, what goes on?

Does it set the culture based on the client browsers Accept-Language?
Does it set the culture based on the server's culture, having all clients use that same culture?
Is it something else?

And if it's per session/circuit, do I need to do anything or does it then have that as the CultureInfo.CurrentCulture / CultureInfo.CurrentUICulture for all calls I make in the context of that session/circuit?

thanks - dave

Hi @David Thielen , From the MS Website, You can achieve globalization and localization features based on Accept-Language header which is set by the browser based on a user's language preferences in browser settings. You can also based on localization culture cookie and route query string. Use of a cookie ensures that the WebSocket connection can correctly propagate the culture. If localization schemes are based on the URL path or query string, the scheme might not be able to work with WebSockets, thus fail to persist the culture. Therefore, the recommended approach is to use a localization culture cookie.

@Xinran Shen - MSFT How does it do this?

Where/how does it read the Accept-Language?

How is this tied to the circuit?

What effect does it have?

Does it set the CultureInfo.CurrentCulture in threads other than the UI thread?

If I want to override the culture set from Accept-Language, how do I?

I know what to do to tell it what localizations I have. I want to understand how it works and what the limitations are.

thanks - dave

Blazor Server automatically reads the Accept-Language header from the client's HTTP request and sets the culture for the user's session. You don't need to manually read the Accept-Language header in your Blazor components. More details you can refer to link.
