Anyone know if any easy way to find out if a site is written in mvc?

And to take it a step further, assuming it is mvc to determine which pieces are asp.net forms?

I know just becau开发者_StackOverflowse they do or dont exist it doesn't mean 100% but it would be nice to have some things to look for certain headers that exist, or even existence of boilerplate code

i.e.(just a forms example):

onsubmit="javascript:return WebForm_OnSubmit();

No, you can't, at least no way that would be reliable, short of emailing the site's developer.

Unless the site developer has removed it, you get a header on each response that indicates the ASP.NET MVC version. I've tried this on three different sites I have using all three versions of MVC and it always appears.

X-Aspnetmvc-Version:1.0
X-Aspnetmvc-Version:2.0
X-Aspnetmvc-Version:3.0

note: StackOverflow removes all of the ASP.NET injected headers as far as I can tell

---

Well, the most obvious clue is that you don't have extensions to urls (like .aspx). Right?

---

The <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="" /> tag does not exist :)

Fire up Fiddler during the use of a website like www.codeplex.com and you can view header information:

The X-AspNetMvc-Version header can be disabled in your Global.asax.cs file:

protected void Application_Start(object sender, EventArgs e)
{
    MvcHandler.DisableMvcResponseHeader = true;
    // ...
}
