# WebTunnel
Pluggable Transport based on HTTP Upgrade(HTTPT)
WebTunnel is pluggable transport that attempt to imitate web browsing activities based on [HTTPT](https://censorbib.nymity.ch/#Frolov2020b).
## Client Usage
Connect to a WebTunnel server with a Tor configuration file like:
```
UseBridges 1
DataDirectory datadir
ClientTransportPlugin webtunnel exec ./client
Bridge webtunnel 192.0.2.3:1 url=https://akbwadp9lc5fyyz0cj4d76z643pxgbfh6oyc-167-71-71-157.sslip.io/5m9yq0j4ghkz0fz7qmuw58cvbjon0ebnrsp0
SocksPort auto
Log info
```
## Running a WebTunnel Bridge
You can help censored users connect to the Tor network by running a WebTunnel bridge, see our [community documentation](https://community.torproject.org/relay/setup/webtunnel/) for more details.
## WebTunnel Client Bridgeline Format
#### url: string
`url` determines the HTTP layer host and path.
It should be an HTTPS protocol URL string that points to the server endpoint where the WebTunnel Bridge is hosted.
#### version: string
`version` determines the version of the server. This allows the client to adjust its protocol based on the options supported on the server side.
#### addr: string
`addr` determines the Network Layer (TCP) endpoint of the server. By default, it is the same as the host with the port from the URL. (lyrebird version)
#### servername: string
`servername` determines the Transport Layer Security (TLS) server name indication. By default, it is the same as the host without the port from the URL.
#### utls: enum
`utls` determines the utls tls client hello fingerpint.
valid vlues are:
- `none` : use go's default tls fingerprint
