## Protocol
A necessary subset of `HTTP 1.0` with following options of request header being supported.

### From client
- Content-Length

### From server
- Content-Length
- Content-Type (only support text/plain image/x-icon text/css text/html)
- Server

### Code
- 200 OK
- 400 BAD REQUEST
- 403 Forbidden
- 404 NOT FOUND
- 500 Internal Server Error
- 501 Method Not Implemented

## Features
1. Serve files
2. CGI
3. Listen on `ipv6`
4. Listen on unix socket
5. Multi-thread

## Compile
```bash
git clone https://github.com/fumiama/simple-http-server.git
cd simple-http-server
mkdir build
cd build
cmake ..
make
make install
```

## Command line usage
```bash
simple-http-server [-d] [-h] [-n host.name.com:port] [-p ] [-q 16] [-r ] [-u ]
```

- **-d**: run as daemon.
- **-h**: display this help.
- **-n**: check hostname and port.
- **-p**: if not set, we will choose a random port.
- **-q**: listen queue length (defalut is 16).
- **-r**: http root dir.
- **-u**: run as this uid.

## CGI usage
When you put an executable file into the web path, the server will call `execl` to run it while passing 3 parameters as below

```c
argv[0] = path; //Path of the executable file
argv[1] = method; //request method (GET/POST)
argv[2] = query_string; //the query string, like "a=1&b=2&c=3"
```

The server will read a `4 bytes` unsigned integer from pipe, indicating the `length` of the remaining content. Then it will send `length` bytes of data to the client directly with nothing being decorated, which means that you need to assemble the HTTP header by yourself.

Here is a CGI example [CMoe-Counter](https://github.com/fumiama/CMoe-Counter)

And its realization is here:
