iRule transforms from raw socket to HTTP POST,

You'd need to calculate the number of bytes in the HTTP payload for the HTTP content-length header--not the length of the TCP payload. You could try subtracting the length of the HTTP headers from the TCP payload size, or just parse the TCP for the length of the HTTP payload.

 

 

If you want more specific suggestions, could you post the iRule and relevant logs showing the issue?

 

 

Thanks,
