      Epic Goal

      • introduce new configuration parameters that will make  ingress controller more customizable in terms of performance and operations
      • the new configurations will include:
      • httpCompression - defines the policy for HTTP traffic compression.
        mimeTypes defines a list of MIME types to which compression should be applied. For example, text/css; charset=utf-8text/htmltext/*image/svg+xmlapplication/octet-streamX-custom/customsub, using the format pattern, type/subtype; [;attribute=value]. The types are: application, image, message, multipart, text, video, or a custom type prefaced by X-; e.g. To see the full notation for MIME types and subtypes, see RFC1341
      • httpHeaders - defines the policy for HTTP headers.By default, the policy is set to Append.
        • Append specifies that the Ingress Controller appends the headers, preserving any existing headers.
        • Replace specifies that the Ingress Controller sets the headers, removing any existing headers.
        • IfNone specifies that the Ingress Controller sets the headers if they are not already set.
        • Never specifies that the Ingress Controller never sets the headers, preserving any existing headers.
      • tuningOptions - specifies options for tuning the performance of Ingress Controller pods see 
      • HTTPEmptyRequestsPolicy - describes how HTTP connections are handled if the connection times out before a request is received. Allowed values for this field are Respond and Ignore. The default value is Respond.
      • Enable/Disable HTTP2 -  
        To enable the use of HTTP/2 for the connection from the client to HAProxy, a route must specify a custom certificate. A route that uses the default certificate cannot use HTTP/2. This restriction is necessary to avoid problems from connection coalescing, where the client re-uses a connection for different routes that use the same certificate.
