This very simple plugin aims at avoiding mixed content when using https for wordpress sites.
<h4>Principle</h4>
When you are using HTTPS for browsing, all content resources will point to https. All ‘http’ references will be changed to ‘https’.
On the contrary, if you want HTTP browsing, all references will be changed to ‘http’, which can be useful if you are behind a proxy that filters https.

Https Switcher

Thanks @janiko for creating this great plugin! It works fantastic on my sites and even your source code looks amazing. Well done!

Simple and yet powerful!

Force http/https for resources, depending on the scheme you use.
