Option to disable MustRevalidate=true

[yringler]

Long story short - why is cache header revalidate always set to true?

ImageSharp.Web/src/ImageSharp.Web/Middleware/ImageContext.cs

Line 203 in d055952

MustRevalidate = true

Should there be a config for that?

You can already update the response headers before a response is sent via ImageSharpMiddlewareOptions.OnPrepareResponseAsync.

ImageSharp.Web/src/ImageSharp.Web/Middleware/ImageSharpMiddlewareOptions.cs

Lines 149 to 166 in d055952

	/// <summary>
	/// Gets or sets the additional response method.
	/// This is called after the status code and headers have been set, but before the body has been written.
	/// This can be used to add or change the response headers.
	/// </summary>
	public Func<HttpContext, Task> OnPrepareResponseAsync
	{
	get
	{
	return this.onPrepareResponseAsync;
	}
	set
	{
	Guard.NotNull(value, nameof(this.OnPrepareResponseAsync));
	this.onPrepareResponseAsync = value;
	}
	}

P.S. ImageSharp Discussions is the wrong discussion channel. I've migrated this for you to the correct one.
