Proxy Authentification with Arduino Uno + Ethernet Shield

Projects Networking, Protocols, and Devices

Hello everybody,
I'm trying to connect my Arduino to the internet, but in our school we use a proxy with authentification enabled. I know that the Arduino doesn't support the usage of a proxy natively.
Does someone have an idea how to send/receive information through a proxy with authentification?
Thanks.

I know that the Arduino doesn't support the usage of a proxy natively.

The Arduino doesn't even support HTTP natively. You use an HTTP client and put the whole URL into the GET request (not only the local path but also the protocol and host name parts) and add the Proxy-Authorization header as specified in RFC2616 (HTTP protocol). You connect to the proxy and not the server the URL is pointing to.

Thanks for the reply, pylon!

How do I add the Proxy-Authorization header?

How do I add the Proxy-Authorization header?

The same way as you add p.e. the "Host" header line. Show us the code you're using if you want more help.
