Networking and F5 Load Balancers

[continuedprogress101]

Good afternoon,

Currently in a situation where a client is sending me tcpdumps every day. They state that they experience intermittent 400 bad request responses. I don't see how this is a networking issue since a TCP handshake is consistently establishing. Is this really a networking issue? Would an F5 load balancer cause this issue?

We need more information, how your network, from where the user trying to send files.

you can gather some Log informaiton on F5 also why this was terminated, and also check on the Web Server why it was generated 400.

Hello,

400 Bad Request errors are almost always client related. Typically you would ask the client which browser (e.g. IE, Chrome, Firefox) is being used, and ask to clear cookies and flush the DNS cache ('ipconfig/ flushdns' on Windows clients). I would also ask if this occurs with specific websites, and if the error occurs when they try to download (large) files...
