$Web_Input_Header
Retrieve web request header contents
$Web_Input_Header retrieves the raw web request headers sent by a client. $Web_Input_Header returns this content as a longstring.
Syntax
%lstr = $Web_Input_Header( [type] )
$Web_Input_Header takes a single optional argument and returns a longstring.
type | A case-independent string set to one of the following:
type is an optional argument, and it defaults to Binary. |
---|
$Web_Input_Header can be used to examine data from the client if the RAWHEADER parameter is set on the port definition.
Web request header parameters are always separated by ASCII carriage-return/line-feed (X'0D0A') pairs. As such, an application using $Web_Input_Header would probably want to parse the returned longstring using longstring parsing functions (see "Longstrings and $functions") or Stringlist class parsing methods (the ParseLines method is likely to be particularly helpful).
$Web_Input_Header is available only in Versions 7.5 and later of Model 204.
