Question: I have a MVC3 application with ASPX view engine. My page is having a dropdownlist created by 

```
Html.DropdownListFor(m=>m.EmpId,(selectlist)Model.EmpDetails).

```

I update this dropdown on a situation where it would have only one item and make that disabled, by Jquery. Now when I go to form post, my model's `'EmpId'` property is not updated with the corresponding value of its selected item in dropdown list. I suspect, since the dropdownlist is not manually selected (updated by Jquery), I'm not getting `'EmpId'` in my model. Is there a way to overcome this issue?

With regards,

Answer: 
You can look at the `Content-Type` HTTP header to figure out what *type* of file you are getting — but you can't find out what the filename used on the server is (or even if there is a filename), and (in most cases) both index.html and default.asp will return an HTML document.
If example.com is a different server than the one PHP is running on, you can't.
OPTION : you can bruteforce, that is trying different possible filenames (index.htm, index.html, index.php, index.asp, default.html, etc...)
