Description

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Is your feature request related to a problem? Please describe the problem.

In the browser the request shows a 200 response but gets a net::ERR_CONNECTION_RESET error.

In the ASP.NET Core logs we see the request finishing with a 200
Request finished HTTP/2 GET - - - 200 - application/json;+charset=utf-8 17292.3150ms|

In the IIS logs I see that the request is logged with a 500.19 error:
2023-12-12 21:06:16 10.18.114.208 GET 6500 - 10.18.114.6 Mozilla/5.0+(Windows+NT+10.0;+Win64;+x64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/120.0.0.0+Safari/537.36 500 19 64 17292

In the HTTPERR log I see a SlowResponsiveClient error code. I cannot find any documentation on what this error means or if it can be configured with any settings:
2023-12-12 21:06:16 10.18.114.6 5921 10.18.114.208 6500 - - - - - - SlowResponsiveClient -

### Describe the solution you'd like

Provide documentation on what the SlowResponsiveClient error means and any means of configuring HTTP.SYS to control this response.
