You can use any tool that can send a HTTP HEAD request and parse the answer.

With curl for example:

# curl -I http://www.codeproject.com

Hi Jochen,
If i add this "X-Content-Type-Options: nosniff" in my web.config the icons are not displaying in IE .
I have searched in google the solution is need to change png format images into jpg format.
Could you please tell me except this, Is there any solution to fix this?
Because i should include X-Content-Type-Options: nosniff in my web.config.

I have not used that and can't help therefore.

But according to https://developer.mozilla.org/de/docs/Web/HTTP/Headers/X-Content-Type-Options:
"Note: nosniff only applies to "script" and "style" types. Also applying nosniff to images turned out to be incompatible with existing web sites."

should it not be applied to image types.
