Then, the reason of this second packet is not sent to the backend is because of the HTTP profile as I mentioned.

What's the problem of using L4 virtual in your environment? This will fix the problem.

There are some bugs regarding TCP Segmentation. If you want to experiment, I recommend you disable TSO and LRO to force software TCP segmentation processing.

Also, you could program your client to use chucking method to send your payload. That will avoid TCP segmentation.

BTW, you can also configure http profile proxy mode as transparent to avoid compliant checking.
