HttpContext .NET core saving instance in Middleware

Is it safe to store an instance of HttpContext in a middleware?

Example:

public class TestMiddleware
{        
    private readonly RequestDelegate next;    
    private HttpContext context;
    public TestMiddleware(RequestDelegate next)
    {
        this.next = next;
    }

    public async Task Invoke(HttpContext context)        
    {
        try
        {
            this.context = context;

I would like to use it in other private methods to work on it, so I can either pass it around as parameter to those function or use it as shown in the example.

But is it thread safe?

No it's not, because middleware are necessarily singletons. If you store a specific HttpContext in a shared field, it will be potentially reused during another request (which would be terrible).
