Description
The Error Report Valve is a simple error handler for HTTP status codes that will generate and return HTML error pages. It can also be configured to return predefined static HTML pages for specific status codes and/or exception types. Disabling "showServerInfo" will only return the HTTP status code and remove all CSS from the default nonerror-related HTTP responses.
