In addition to showing the response, you can see the t this response, and some response codes. Note that the Request panel only shows the headers added by JMeter. It does not show any headers (such as Host) that may be added by the HTTP protocol implementation. +

    For HTTP samples the Request panel also provides a cURL tab that renders the request as a ready-to-run curl command, so it can be copied to a console or shared with a developer. +The command targets a POSIX-compatible shell (it is not valid cmd.exe or PowerShell syntax). +It reproduces whatever the sample carried, including Authorization headers, cookies and API keys, +so treat it as sensitive when sharing. Multipart uploads are rendered as -F form parts using the +original field and file names; since JMeter does not keep the uploaded bytes, a file is referenced as +@filename, a placeholder to edit to a real path before running the command. A file sent as the +whole request body, or a non-repeatable body, cannot be shown at all and is omitted with a note.

    There are several ways to view the response, selectable by a drop-down box at the bottom of the left hand panel.
