The HTTP request message is url-encoded per default. This means that
non-alphanumerical characters are converted into %hh-strings where „hh“
represents a hexadecimal gure. The lines ‘&&’ and ‘==’ are an exception:
these are converted into ‘&’, and ‘=’ respectively. The message for the HTTP
request is transmitted via the request header POST, or else added to the
URL of the GET request. In that case, the separating sign ‘?’ is added bet-
ween the URL and the message.
