如何检测GET请求是来自AJAX请求还是浏览器请求？

Question

I am writing an app using requireJS and the text.js extension. I now have a bunch of unstyled html templates that get their style once they are loaded into the parent template. Everything works fine. The only issue I have is that users can technically visit the url of the template and see an unstyled html page. Is there anyway to detect that these requests come from an AJAX request invoked by javascript vs a request that came directly from the user using a browser?

It depends on how you are making the AJAX requests but most frameworks add some custom header. For example jQuery adds the X-Requested-With: XMLHttpRequest request header on each AJAX request. This header can be used on the server to determine whether it was an AJAX request or not. And if the framework you are using to make an AJAX request doesn't add any custom headers you could add one manually yourself.
