Thanks for reporting this. Can you give some more details?

• Which version of HAProxy
• Sample of HAProxy config
• Is the HTTP request constructed in any special way? (e.g. curl, if so, what's the command)

Possibly related to #23 and #18

I am not seeing this error when I test. If possible, please give more details about how you're getting the error.

I've reproduced it. If you send an OPTIONS request that is not a preflight request. I will fix it.
