// ExtendHttpRequestHeaderValueRule An object that represents the action of modifying a request header value. This rule applies only to HTTP listeners.
// This rule adds a prefix, a suffix, or both to the header value.
// **NOTES:**
//   - This rule requires a value for a prefix, suffix, or both.
//   - The system does not support this rule for headers with multiple values.
//   - The system does not distinquish between underscore and dash characters in headers. That is, it treats
//     `example_header_name` and `example-header-name` as identical.  If two such headers appear in a request, the system
//     applies the action to the first header it finds. The affected header cannot be determined in advance. Oracle
//     recommends that you do not rely on underscore or dash characters to uniquely distinguish header names.
