How can I control a WiFi receptacle/switch from my own webpage?

I'm looking for a WiFi controlled wall receptacle or switch that I can control from my own webpage. All the options that I have seen either have a proprietary remote control switch or an Android app to control the device. Are there any WiFi receptacles or switches that allow independent control from my own webpage? Thanks for any suggestions.

 

I wouldn't use this for mission critical things, but I've seen this service used to tie web pages to physical devices:

I have a HomeKit switch that I use, but that probably wouldn't help you too much. Look into home automation products such as X10.

When you say "my own webpage", do you mean a website on a server you control? If your site is hosted on a remote server (like GoDaddy or many others), you'll need a way to route a click on your site to your switch. It would be easy to trigger sending an e-mail or send a notification but it wouldn't be as easy to pass some other command directly over IP. The server would have to be running a service to enable such a thing.
