# 3. – Setting up parameter with HTTP header or HTTP basic authentication for VPN integration

SparkView also supports the following parameters from HTTP Headers:
```
gw_server: The RDP server address.
gw_port: RDP server port
gw_user: username of RDP server
gw_pwd: password of RDP server
gw_symlink: the symlink id
```
You can also set `authorization = Basic` in gateway.conf to enable HTTP Basic Authentication on SparkView.

**Pros:** easy and simple for SSO<br>**Cons:** Need VPN or proxy to set up the HTTP headers.
