InvokeAsync Method

Namespace

Assemblies

Source

src/Cuemon.AspNetCore/Http/Headers/VaryAcceptMiddleware.cs

InvokeAsync(HttpContext)

Invokes the middleware for the given HttpContext. Adds the Vary: Accept response header just before the response starts.

public override Task InvokeAsync(HttpContext context)

Parameters

context HttpContext

The current HttpContext.

Returns

Task

A Task that represents the asynchronous operation of this middleware. The returned task completes when the remaining pipeline has finished processing.

Remarks

The header is appended using OnStarting(Func<Task>) to ensure the header is present even if the response body is being streamed or the response was started by downstream middleware. This signals to intermediaries and clients that the response representation depends on the request's Accept header.
