$Web Hdr Parm Lstr

<section begin="desc" />Value of header parameter to longstring<section end="desc" />

$Web_Hdr_Parm_Lstr retrieves the value of an HTTP header parameter as a longstring.

Syntax

<section begin="syntax" /> %STRING = $Web_Hdr_Parm_Lstr( name, occurrence ) <section end="syntax" />

$Web_Hdr_Parm_Lstr takes two arguments, and it returns a longstring (or null for any error condition).

name	The name of the header parameter, returned by $Web_Hdr_Name. This is a required argument if occurrence is not specified; otherwise it is optional.
occurrence	The occurrence number of a header parameter, or the occurrence number of the header parameter matching name, if name is specified. Optional argument if name is specified, otherwise it is required.

This example places the value of two header parameters into a User Language Longstring variable of the same name.

%accept = $Web_Hdr_Parm_Lstr('ACCEPT') %referer = $Web_Hdr_Parm_Lstr('REFERER')

$Web_Hdr_Parm_Lstr works much like $WEB_HDR_PARM, except for the following:

• It can return more than 255 bytes of data into a longstring.
• It causes request cancellation if the result would be truncated, either on assignment to a target STRING %variable, or as input to a STRING $function argument or subroutine parameter.
• It does not have position and length arguments (arguments 3 and 4).

$Web_Hdr_Parm_Lstr is only available in Sirius Mods Version 6.7 and later.

For more information about longstrings, see the Sirius Functions Reference Manual.
