Content-Location header indicates an alternate location for the returned data. The principal use is to indicate the URL of a resource transmitted as the result of content negotiation.
Content-Location are different.
Location indicates the URL of a redirect, while
Content-Location indicates the direct URL to use to access the resource, without further content negotiation in the future.
Location is a header associated with the response, while
Content-Location is associated with the data returned. This distinction may seem abstract without examples.

Requesting data from a server in different formats
Let's say a site's API can return data in JSON, XML, or CSV formats. If the URL for a particular document is at
https://example.com/documents/foo, the site could return different URLs for
Content-Location depending on the request's
|Request header||Response header|
These URLs are examples — the site could serve the different filetypes with any URL patterns it wishes, such as a query string parameter:
/documents/foo?format=xml, and so on.
Then the client could remember that the JSON version is available at that particular URL, skipping content negotation the next time it requests that document.
Pointing to a new document (HTTP 201 Created)
Say you're creating a new blog post through a site's API:
PUT /new/post Host: example.com Content-Type: text/markdown # My first blog post! I made this through `example.com`'s API. I hope it worked.
The site returns a generic success message confirming the post was published. The server specifies where the new post is with
HTTP/1.1 201 Created Content-Type: text/plain; charset=utf-8 Content-Location: /my-first-blog-post ✅ Success!
Indicating the URL of a transaction's result
Say you have a
<form> for sending money to another user of a site.
<form action="/send-payment" method="post"> <p> <label>Who do you want to send the money to? <input type="text" name="recipient"> </label> </p> <p> <label>How much? <input type="number" name="amount"> </label> </p> <button type="submit">Send Money</button> </form>
When the form is submitted, the site generates a receipt for the transaction. The server could use
Content-Location to indicate that receipt's URL for future access.
HTTP/1.1 200 OK Content-Type: text/html; charset=utf-8 Content-Location: /my-receipts/38 <!doctype html> (Lots of HTML…) <p>You sent $38.00 to ExampleUser.</p> (Lots more HTML…)
