Url fragment and Referer header
Imagine you are on a page whose URL has a fragment (the part a开发者_C百科fter the #
), and click a link to go to another page. Most browsers will send the URL of the original page to the server in the Referer
header. What I want to know is whether or not the URL fragment will be included in this or not.
I have seen various behaviors in the wild so this might be browser-specific. Does anyone know which browsers do what? And what does the HTTP spec say on this?
The spec says that Referer can't include a fragment identifier (per ABNF). See RFC 2616, Section 14.36.
I saw the same behavior in IE today. I am using IE 11.0.9600.17801 and upon inspection i found out that the 'Referer' header contains this fragment identifier.
Referer: //abc:8080/myapp/ver/index.htm#search-basics
Although I am quite certain that I have seen this behavior on and off with the same browser.
The spec says basicly that you can do whatever you want - it is an optional header, i just tested webkit ignores the fragment, as do firefox and IE.
