About the 'echo' script

The HTTP 'echo' script just reads your HTTP request and echoes it back to you as the content of a response.  The response is of type "text/plain".  However, the script doesn't always exactly represent what was sent across the network.  Please note the following:

• Obviously your request URL must be http://djce.org.uk/utils/echo.cgi or similar.
• The script must be requested using either GET or POST.
• The order of HTTP headers is not preserved.
• The processing of repeated HTTP headers (i.e. if any given header tag appears more than once in your request) is not defined.
