Describe the bug

An encoded url parameter looks decoded by WireMock server. My code sends a request like : POST http://localhost:4200/api/file%3Atest.pdf to Wiremock proxy server. The url is then transformed to POST https://webservie.com/api/file:test.pdf. Here the url encoded parameter file%3Atest.pdf is decoded and forwarded as file:test.pdf which generate an error from the webservice

I

Expected behavior:

I expect that encoded url parameter are not decoded

Test to reproduce

Create a mock server with proxy (here is my code)

MockServer = WireMockServer.Start(new WireMockServerSettings
{
    Urls = [BaseProxyURL],
    FileSystemHandler = new LocalFileSystemHandler(recordingPath),
});

MockServer
    .Given(Request.Create().WithPath($"*/service/*"))
    .RespondWith(Response.Create()
        .WithProxy(new ProxyAndRecordSettings
        {
            Url = "https://webservice.com/",

            SaveMapping = true,
            SaveMappingToFile = true,
            ExcludedHeaders = ["Authorization"],
            ReplaceSettings = new ProxyUrlReplaceSettings
            {
                OldValue = $"/service",
                NewValue = ""
            }
        })
    );

Capture the outbound traffic with fiddler
Send a request containing an encoded url parameter
