Seeing odd HTTP method causing PHP Out of Memory


I have recently been seeing requests coming in with a HTTP method of “POST-BYPASS” which after numerous requests seems to be causing PHP to run out of memory for a short while (and subsequently take the site offline). While this has not caused any major issues for our site, I have gone on to add a specific firewall rule to block non-standard HTTP methods. Has anyone seen this before? Should Cloudflare not block these by default or am I missing something?


That method does not seem to be mentioned anywhere but I guess Cloudflare wont block it because it supports custom HTTP methods.
