[ionmincu]

Library name and version

Azure.Monitor.OpenTelemetry.Exporter 1.3.0-beta

Describe the bug

I've added http.url and url.full but I do not see the full url with patbase in requests table

        builder.Services.Configure<AspNetCoreTraceInstrumentationOptions>(options =>
        {
            options.EnrichWithHttpResponse = (activity, httpResponse) =>
            {
                // remove query string as it may contain sensitive data 
                activity.SetTag("url.query", string.Empty);
 
                // add this at the end to override with Forwarded headers if present
                var request = httpResponse.HttpContext.Request;
                activity.SetTag("server.address", request.Host.Host);
                activity.SetTag("server.port", request.Host.Port);
                activity.SetTag("url.scheme", request.Scheme);
                activity.SetTag("url.full", $"{request.Scheme}://{request.Host}{request.PathBase}{request.Path}");
                activity.SetTag("http.url", $"{request.Scheme}://{request.Host}{request.PathBase}{request.Path}");
            };
        });

Expected behavior

See full url including pathbase

Actual behavior

I only see $"{request.Scheme}://{request.Host}{request.Path}");

Reproduction Steps

Create a webapp with app.UsePathBase(/mypath) and make requests to /mypath/api/controller you will only see http://server/api/controller

Environment

No response
