iPhone 6 – Header 'Connection' contains invalid values

  • Hi

    We’ve had a few reports from users of different websites that use the Bad Behaviour plugin of being blocked and getting the 400.

    The persistent error is:

    Header ‘Connection’ contains invalid values

    With user agent:

    User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 8_3 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) Mobile/12F70

    After looking at headers one thing that seemed possible is that HTTP_CACHE_CONTROL is empty but I don’t know why it’s so sporadic or what I can do with these clients who can’t access their own sites.

    Great plugin besides this though! ??

    …Oh – and as the subject suggests they are using iPhone 6

    Hmm. I’ve now had an instance where HTTP_CACHE_CONTROL wasn’t empty but was still blocked. So not seeing a pattern apart from iPhone 6’s – although some are ok.

    I just had the same issue on iPhone 4s.

    So far all problems are coming from phones using Vodafone but that’s just weird…

    I just read this:

    Having had a closer look at the criteria Bad Behaviour uses, it looks like it’ll automatically block anyone seen to be connecting from multiple IP addresses, or making multiple requests from the same IP address. Since a single public IP address on our network is shared simultaneously with thousands of other users, this is making any Vodafone user appear as if they are a “bot” and causing them to be blocked automatically, regardless of whether you disconnect or reconnect.

    Although this is about 5 years old I can see this being an issue.

    If anyone knows of anything that can be done about this I would be most grateful!
