Hi,

We am having an issue with our site, when a customer is trying to edit the cart contents on really large carts (50 different products or more) he get's an screen with the error: ERR_RESPONSE_HEADERS_TOO_BIG. When you reload the page you see that the cart contents has been updated. This happens on Chrome only.

I disabled the Keep Visitors Cart option in the Configuration->Sessions area and it seems to work, but we are losing sales now. (A lot of sales).

I changed some server values (like LimitRequestFieldSize) to a bigger size and this doesn't solve the problem either.

So. Two questions,
Is there a way to solve this? or
Is there a module or contribution that saves the cart to the database or a flat file instead of a cookie so headers can be smaller?

INFO:
Site: https://www.quikdrawers.com/ (Lots of plugin and custom code in there).

Thanks for any help and forgive the bad English.

Best regards.
