Compressed files are not server when StaticFileOptions has RequestPath

Ratioanle

If StaticFileOptions has RequestPath path specified and static files are queried as {RequestPath}/path-to-a-static-file then cached versions are not served.

It says that originalFile doesn't exist

CompressedStaticFiles/src/CompressedStaticFiles/CompressedStaticFileMiddleware.cs

Lines 99 to 104 in 424d6fd

    
           var originalFile = fileSystem.GetFileInfo(context.Request.Path); 
        
           if (!originalFile.Exists) 
        
           { 
        
               return; 
        
           }

Test

        [TestMethod]
        public async Task Should_serve_the_compressed_file_if_a_compressed_version_exists_and_the_browser_supports_it()
        {
            // Arrange
            var builder = new WebHostBuilder()
                .Configure(app =>
                {
                    app.UseCompressedStaticFiles(new StaticFileOptions
                    {
                        RequestPath = "/assets"
                    });
                    app.Use(next =>
                    {
                        return async context =>
                        {
                            // this test should never call the next middleware
                            // set status code to 999 to detect a test failure
                            context.Response.StatusCode = 999;
                        };
                    });
                }).UseWebRoot(Path.Combine(Environment.CurrentDirectory, "wwwroot"));
            var server = new TestServer(builder);

            // Act
            var client = server.CreateClient();
            client.DefaultRequestHeaders.Add("Accept-Encoding", "br, gzip");
            var response = await client.GetAsync("/assets/i_also_exist_compressed.html");
            var content = await response.Content.ReadAsStringAsync();

            // Assert
            response.StatusCode.Should().Be(200);
            content.Should().Be("br");
            response.Content.Headers.TryGetValues("Content-Type", out IEnumerable<string> contentTypeValues);
            contentTypeValues.Single().Should().Be("text/html");
        }

This would be nice to get fixed.

@msschl @ilyapalkin sorry for the huge delay but 2.1.0 is on its way and includes a fix for this

	var originalFile = fileSystem.GetFileInfo(context.Request.Path);

	if (!originalFile.Exists)
	{
	return;
	}
