Error loading metadata xml file on Firefox

Non Security Issues

There appears to be an issue with how the XML file is being provided for MetadataCommand - this is working without issue on Chrome, but on Firefox it fails with connection reset (NS_ERROR_NET_RESET). This was reproduced with the sample project here with no modifications: https://github.com/Sustainsys/Saml2.Samples

• Run the AspNetCore project
• Open (for example) http://localhost:7196/Saml2 in Firefox / Chrome

Additional info

Target .NET frameworks: net6.0;net7.0 Installed .NET frameworks: net6.0;net7.0;net8.0 Firefox version: 129.0

I can investigate further and try to find the cause of the problem / open a PR
