Modify, add, remove, or pass along specific request headers coming upstream from the client.

Depending on the type of action you want to perform, specify the corresponding standard header name, or a custom_header_name if the standard name is set to OTHER. The header_value serves as a match condition when the action is DELETE or MODIFY, and the new_header_value applies when the action is ADD or MODIFY.
