Hi all,

I got a weird behavior with apache 2.4.12 (from RHEL scl for that matter).

I have a php application (behind fcgi/fpm) that sets Last-Modified header like:

<?php header('Last-Modified: never');

but when I curl the page, the header sent is:

< Last-Modified: Thu, 01 Jan 1970 00:00:00 GMT

When the date is correct in my php app, the returned value is OK but as soon as it's not RFC valid, it's modified.

I am probably missing some bits of information, but what is the use case to send a HTTP response with a well known header not following the RFC? I didn't check the code but I would expect httpd to enforce the RFC when needed rather than simply returning what the backend issues. 

Thanks!

Luca
