$Web_Hdr_Parm_Lstr
Value of header parameter to longstring
$Web_Hdr_Parm_Lstr retrieves the value of an HTTP header parameter as a longstring.
$Web_Hdr_Parm_Lstr takes two arguments, and it returns a longstring (or null for any error condition).
Syntax
%string = $Web_Hdr_Parm_Lstr( name, occurrence )
Syntax terms
| 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. |
Usage notes
- $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).
Examples
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')
