If you encounter a 400 Bad Request error on mediacast.smu.edu.sg, you can clear the cookies for that specific site instead of clearing your entire browser cache. This allows you to resolve the issue without being signed out of other websites and services.
Note: These instructions are based on Chromium-based browsers such as Microsoft Edge and Google Chrome.
Step 1: Open the affected website
Navigate to mediacast.smu.edu.sg and ensure the page displaying the error is open.
Step 2: Open Developer Tools
Right-click anywhere on the page and select Inspect (or Inspect Element).
A Developer Tools panel will appear on the side or bottom of your browser window.
Step 3: Go to the Application tab
At the top of the Developer Tools panel, click the Application tab.
If you do not see the Application tab, click the >> (double-chevron) icon to reveal additional tabs.
Step 4: Locate the site's cookies
In the left-hand navigation panel, expand Storage (if required) and then expand Cookies.
You will see one or more domain entries listed underneath.
Step 5: Clear cookies for the affected domain
Locate the relevant domain (for example, mediacast.smu.edu.sg or related .smu.edu.sg entries).
Right-click the domain and select Clear.
This removes only the cookies associated with that domain.
Step 6: Refresh the website
Return to the browser tab and refresh the page (F5 or Ctrl+R).
The website should now reload with a fresh set of cookies.
Why this works
The 400 error is often caused by excessive cookie data associated with the .smu.edu.sg domain. By clearing cookies for the affected site, the browser removes the accumulated data that may be causing the request to exceed the size limits accepted by the server.
Unlike clearing your entire browser cache, this approach is more targeted and helps minimise the need to sign in again to other websites and applications.
