# The-Basics

## Overview

Gor architecture tries to follow UNIX philosophy: everything made of pipes, various inputs multiplexing data to outputs.

You can [rate limit](https://app.gitbook.com/s/-MOSMqWJv57pGTOWPxHf/untitled/Rate-limiting), [filter](https://app.gitbook.com/s/-MOSMqWJv57pGTOWPxHf/untitled/Request-filtering), [rewrite](https://app.gitbook.com/s/-MOSMqWJv57pGTOWPxHf/untitled/Request-rewriting) requests or even use your own [middleware](https://app.gitbook.com/s/-MOSMqWJv57pGTOWPxHf/untitled/goreplay.wiki/Middleware) to implement custom logic. Also, it is possible to replay requests at the higher rate for [load testing](https://app.gitbook.com/s/-MOSMqWJv57pGTOWPxHf/untitled/Saving-and-Replaying-from-file).

## Available input and output plugins

Available inputs:

* `--input-raw` - used to capture HTTP traffic, you should specify IP address or interface and application port. More about \[\[Capturing and replaying traffic]].
* `--input-file` - accepts file which previously was recorded using `--output-file`. More about \[\[Saving and Replaying from file]]
* `--input-tcp` - used by Gor aggregation instance if you decided forward traffic from multiple forwarder Gor instances to it. Read about using \[\[Aggregator-forwarder setup]].

Available outputs:

* `--output-http` - replay HTTP traffic to given endpoint, accepts base url. Read [more about it](https://app.gitbook.com/s/-MOSMqWJv57pGTOWPxHf/untitled/Replaying-HTTP-traffic)
* `--output-file` - records incoming traffic to the file. More about \[\[Saving and Replaying from file]]
* `--output-tcp` - forward incoming data to another Gor instance, used in conjunction with `--input-tcp`. Read more about \[\[Aggregator-forwarder setup]].
* `--output-stdout` - used for debugging, outputs all data to stdout.
