You can try the header_rewrite plugin https://docs.trafficserver.apache.org/en/latest/admin-guide/plugins/header_rewrite.en.html
I don't know too well whether TS 4.2.3's header_rewrite plugin has enough features for your needs. But I believe the latest ones does have everything you need. You can also use the ts_lua plugin as well if you are using later version of trafficserver. Thanks.
