Infinite loop on sub path redirects

[Gronex]

If i have a redirect like /catalog-content -> /catalog-content/true-catalog i enter a loop.

If i submit fx /catalog-content, the first redirect will lead me to /catalog-content/true-catalog, which will then send me to /catalog-content/true-catalog/true-catalog. This repeats until the browser stops it.

I updated the test case that is checking for it to make sure it was not something else in our environment, and this version does reproduce the issue:

        [Fact]
        public async Task Request_does_not_build_forever()
        {
            var builder = new RedirectServerBuilder();

            builder.AddRedirect("/catalog-content", "/catalog-content/true-catalog");
            builder.AddRedirect("/catalog-content/nice-sweater", "/catalog-content");
            builder.AddRedirect("/catalog-content/redirect-by-code", "/catalog-content/nice-sweater");

            using var server = builder.Build();
            using var client = server.CreateClient();

            var response = await client.GetAsync("/catalog-content/redirect-by-code");

            Assert.NotNull(response);
            Assert.Equal(HttpStatusCode.MovedPermanently, response.StatusCode);

            var location = response.Headers.Location?.ToString();
            Assert.Equal("/catalog-content/nice-sweater", location);

            var iterations = 0;

            while (response.StatusCode == HttpStatusCode.MovedPermanently)
            {
                response = await client.GetAsync(location);
                location = response.Headers.Location?.ToString();

                Assert.True(++iterations < 100);
            }
        }

In the old test the name of the subpath was the same as the root, which apparently does act as it should.
