Invalid Http response header, retry!

[doniking]

Hello,

I always get this WARN log on Litespeed Load Balancer:
Invalid Http response header, retry!
Could you please explain and how to avoid this?

Thanks.

That error means that the backend does not send back a valid HTTP response header. It might be a result of previous canceled request and the connection has not been closed for some reason, and previous request has been buffered? We will investigate.
However, this message won't affect anything as the connection was closed immediately and retried again.

previously the Load Balancer always return only half of the page.
i thought it was caused by this warning. after doing some tunes, it goes normal but still getting this warning.

Nothing to worry about this warning.

OK, thank you.
