How to save page load performance in blazor when navigating from one page to other in new tab?

Question

If a Blazor app with Individual user accounts is created then if we open a new line user Authorization is performed again which impacts the performance and page load.

for example: if we show a document anchor tag, then if that anchor opens in a new tab the full blazor lifecycle is performed including the Authorization of the user. Can we avoid this by maintaining user sessions a bit differently?

Answer 1

loading an blazor app into a new tab requires creating a new blazor instance, and rerunning the authentication logic.

if you are using cookie authentication (blazor server), you can reduce the logic by requiring the blazor hosting page to require authorization. if the original cookie has not expired, it will not need to redirect to the long service. if you are storing jwt tokens, then you want a persistent store keyed by the username key.

if you are using blazor WASM, you can store the authentication tokens in localstorage, and check first at load (need custom authentication state provider).
