+### Replay Responses to a Proxy based on Status Code (new in `v1.5.0`)
+
+The `--replay-proxy` and `--replay-codes` options were added as a way to only send a select few responses to a proxy.  This is in stark contrast to `--proxy` which proxies EVERY request.  
+
+Imagine you only care about proxying responses that have either the status code `200` or `302` (or you just don't want to clutter up your Burp history).  These two options will allow you to fine-tune what gets proxied and what doesn't.  
+
+```
+./feroxbuster -u http://127.1 --replay-proxy http://localhost:8080 --replay-codes 200 302 --insecure
+```
+
+Of note: this means that for every response that matches your replay criteria, you'll end up sending the request that generated that response a second time.  Depending on the target and your engagement terms (if any), it may not make sense from a traffic generated perspective.
