I am trying to find how can I detect with JavaScript if I am in a HTTP or HTTPS environment.

I am calling an Ajax request so if I am in HTTPS and call HTTP Ajax then I get a 302 Moved Temporarily.

I was thinking of getting the current window.location.href and do a string manipulation.

What is the best way of detecting HTTPS using JavaScript?

You can use the non-standard

window.location.protocol

In IE, it seems to be

 document.location.protocol

I can't find reliable info on how this behaves on other browsers, but I expect they adhere to the quasi-standard of document.location.protocol.

Maybe the jQuery url plugin sorts this out without having to deal with cross-browser differences - I've never used it myself, but it looks promising:

jQuery.url.attr(protocol);
