Proxying with SSL Not Working in .NET Core 3.1

[xadvfh]

Describe the bug

I am trying to create a proxy with SSL enabled but keep getting the error {"status":"The header name format is invalid."}.

Expected behavior:

Proxy with ssl works.

Test to reproduce

• 1 Create proxy with:

            WireMockServer.Given(Request.Create()
                        .UsingAnyMethod())
                        .AtPriority(100)
                .RespondWith(Response.Create()
                        .WithProxy(proxyUrl));

• 2 Start server with ssl enabled
  -3 Navigate to https://localhost:[your-port]

Other related info

1. Proxy without SSL works
   2, I am able to proxy with ssl via the Java version of wiremock so I know it's nothing to do with the website I am proxying to.

@StefH any ideas on this issue?

@xadvfh
I did test with my test-app: WireMock.Net.Console.NETCoreApp3

And with this mapping:

            server
                .Given(Request.Create().WithHeader("ProxyThisHttps", "true")
                    .UsingGet())
                .RespondWith(Response.Create()
                    .WithProxy("https://www.google.com")
            );

Works fine when I access my wiremock on https://localhost:9433 in postman-->

However I do get an error that my certificate is not valid, but that's expected:

Does this help you @xadvfh , or do you still have issues?

[xadvfh]

my apologies @StefH I didn't get notifications for this. I will try this out sometime this weekend or early next week and get back to you.

@StefH this is still not working for me. I made a very simple program in another solution:

using System.Threading;
using WireMock.RequestBuilders;
using WireMock.ResponseBuilders;
using WireMock.Server;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            var server = WireMockServer.Start(ssl: true, port: 10080);

            server
                .Given(Request.Create()
                    .UsingAnyMethod())
                .RespondWith(Response.Create()
                    .WithProxy("https://www.google.com"));

            // open browser and point to https://localhost:10080
            Thread.Sleep(60000);
        }
    }
}

[StefH]

Instead of Thread.Sleep use:

System.Console.WriteLine("Press any key to stop the server");
System.Console.ReadKey();
server.Stop();

Works fine for me:

Still not working. What could I be doing wrong?

[StefH]

Are you using .NET Framework or .NET Core?

[xadvfh]

.NET core

OK Thanks for the information.
Issue is related to .NET Core 3.1, it seems that headers starting with a ":" give problems.

PR = #547

Can you try version 1.3.7-ci-14243.nupkg from MyGet (https://github.com/WireMock-Net/WireMock.Net/wiki/MyGet-preview-versions).

[xadvfh]

@StefH that worked! thanks!

[StefH]

@xadvfh -> a new official version will be released today.

[xadvfh]

tested and works in the official new version. thanks again.
