Full Version: Adding Akamai Pragma headers breaks LCP reporting
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
Here are two tests I ran, one with Akamai headers and one without.

Akamai headers added - https://www.webpagetest.org/result/20081...f57a34772/

No headers - https://www.webpagetest.org/result/20081...9b6c655c5/

With Akamai headers, quite a few requests were not loaded and LCP wasn't reported. There are few more things, however the gist is same. The test doesn't work properly. For the record, these tests were scheduled using UI and headers were added under "Advanced > Custom headers". Here is the string that was provided by Akamai.
Code:
Pragma: akamai-x-cache-on, akamai-x-cache-remote-on, akamai-x-check-cacheable, akamai-x-get-cache-key, akamai-x-get-true-cache-key, akamai-x-get-extracted-values, akamai-x-get-ssl-client-session-id, akamai-x-serial-no, akamai-x-get-request-id
