# Dynamic S3 address-style routing prototype

Prototype of dynamic routing for path-style and virtual-hosted-style requests
implemented with go-chi framework.

## Build

```
$ make
```

## Run

### Default setting. 

VHS is disabled. VHS can be overridden by HTTP Header.

```
$ ./bin/chi-s3-vhs

$ curl bucketA.localhost:44412/bucketB/obj
bucket:[bucketB] object:[obj]

$ curl -H "X-FrostFS-VHS: enabled" bucketA.localhost:44412/bucketB/obj
bucket:[bucketA] object:[bucketB/obj]
```

### Global VHS

VHS can be overridden by HTTP Header

```
$ ./bin/chi-s3-vhs --global

$ curl bucketA.localhost:44412/bucketB/obj
bucket:[bucketA] object:[bucketB/obj]

$ curl -H "X-FrostFS-VHS: disabled" bucketA.localhost:44412/bucketB/obj
bucket:[bucketB] object:[obj]
```

### Namespace override

Namespace setting may override default value, but not header value

```
$ ./chi-s3-vhs --global --ns foo=disabled

$ curl bucketA.localhost:44412/bucketB/obj
bucket:[bucketA] object:[bucketB/obj]

$ curl -H "X-FrostFS-Namespace: foo"  bucketA.localhost:44412/bucketB/obj
bucket:[bucketB] object:[obj]

$ curl -H "X-FrostFS-Namespace: foo" -H "X-FrostFS-VHS: enabled"  bucketA.localhost:44412/bucketB/obj
bucket:[bucketA] object:[bucketB/obj]
```
