Steps to reproduce

We are trying to leverage prefetch link to improve speed. It works fine. However, for the prefetched link, there is no specific header indicates that the link is prefetched.

User-Agent Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E)

Steps to reproduce:

  1. Load the page which programmatically insert prefetch link after window onload.
  2. Check header of prefetched link from httpwatch, there is no specific header indicates that link is prefetched.

Is this expected? How to differentiate prefetched link and regular request?
