Use "client_header_timeout" for all requests in a connection. Previously, only the first request in a connection used timeout value from the "client_header_timeout" directive while reading header. All subsequent requests used "keepalive_timeout" for that. It happened because timeout of the read event was set to the value of "keepalive_timeout" in ngx_http_set_keepalive(), but was not removed when the next request arrived.
