            Bug ID: 257298
           Summary: Web Inspector: Network Preserve Log loses 302 redirect
                    to same URL
           Product: WebKit
           Version: Safari 16
          Hardware: Mac (Apple Silicon)
                OS: macOS 12
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Inspector
          Assignee: webkit-unassigned at lists.webkit.org

Twitter redirect

Steps to reproduce:
1) Open a new Safari private window
2) Open the web inspector to the Network tab
3) Enable Preserve Log
4) Open https://twitter.com/webkit/status/1658940299950039047

Expected Results: The Network log shows the 302 redirect.

Actual Results: The Network log doesn't show the 302 redirect.

Notes: Twitter now requires cookies to be enabled in order to view a tweet. You can see this with curl:

% curl -i 'https://twitter.com/webkit/status/1658940299950039047'
HTTP/2 302 
date: Thu, 25 May 2023 00:59:34 GMT
perf: 7626143928
vary: Accept
server: tsa_b
location: /webkit/status/1658940299950039047
set-cookie: guest_id_marketing=

It tries to set cookies and redirects to the same URL. But the web inspector does not reflect this. It only shows the request with cookies, but doesn't show the initial request without cookies or the 302 redirect. See the attached screenshots, one with a same-URL redirect and one with a regular redirect.
