# Custom Protocols
If you want, you can actually create your own protocols to use for your website instead of http or https.
You can register your website to work with any protocol, including custom ones that you create.
Here is the list of reserved protocols.
- bitcoin
- geo
- im
- irc
- ircs
- magnet
- mailto
- mms
- news
- nntp
- openpgp4fpr
- sip
- sms
- smsto
- ssh
- tel
- urn
- webcal
- wtai
- xmpp
Here is the simple method to call to register any protocol.
navigator.registerProtocolHandler(
`web+cheese`,
`http://www.example.com/food.html?type=%s`,
`Title`
);

That code would now prompt the user to allow the registration of the protocol. Assuming that this code is running on the website www.example.com. If the user accepted the registration, then they can use links like:
<a href="web+cheese:mozzarella">Mozzarella</a>

The value of the href would then be passed to the website's food.html page in the querystring parameter type.
