Request Header Or Cookie Too Large - blocked by cloudflare

[hebrian.vasyl]

Hi,
I’m getting

# 400 Bad Request

Request Header Or Cookie Too Large
---
cloudflare

it’s from Cloudflare and not my server, because when I disable Cloudflare proxy it works.

You can repoduce it, visit this page: kochut[.]org/test.php
and refresh it 5-7 times.

it happens only on customer support managers PC, because they have some external plugins.
So I’d like somehow bypass cloudlfare for them, based on cookie/IP/other param.
I can identify them, but I don’t know how to disable proxy for them.

or if I upgrade to Pro plan, could it solve an issue?

You can’t change this limit - you’ll simply need to resolve the issue you have with excessively long cookies or disable Cloudflare.
