How can write an incoming request contents to a file

  • 1.  How can write an incoming request contents to a file

    We get a 400 error on a request with the msg "Malformed request", will like to capture the incoming request and examine.

    There is an included diagnostic module for this that is easy to activate and produces plaintext output:

    If you have difficulty reading the hexdump-like output, the file can be parsed by downloading the IHS mustgather "ihsdiag" and running the "ParseNetTrace" sub-tool. It will create many files in the filesystem for data sent/recvd on different connections.

    If you can't find the issue with the 400, the error_log and nettrace could be analyzed quickly in a support case.
