HTTP headers | Link

For serialising one or more links in HTTP headers, the HTTP Link header-field is used. It allows the server to point an interested client to another resource containing metadata about the requested resource. It is semantically equivalent to the HTML <link> element. 

Link: <uri-reference>; param1="value1" param2="value2"

Directive: This header accept a single directive as mentioned above and described below. The link header contains parameters, which are separated with ; and are equivalent to attributes of the <link> element. 

  • <uri-reference>: The URI reference, must be enclosed between < and >. 


  • This means that more information about the requested resource is available in the resource whose relative URI is
Link: <>; rel="preconnect"
  • The URI must be enclosed between < and >. So, this is not a good way to write.
Link:; rel="preconnect"

Specifying multiple links:  You can specify multiple links separated by commas. 


Link: <>; rel="preconnect", 
<>; rel="preconnect", 
<>; rel="preconnect"

Typical uses are: 

  • A map of different language, content-type and version-specific URIs
  • Licensing, such as Creative Commons
  • Information about how to edit the file
  • Policy information about appropriate use and/or distribution of the data

Supported Browsers: The browser supported by HTTP-header  link are unknown till now.
