$Web Get Cookie Lstr

Value of cookie to longstring

$Web_Get_Cookie retrieves the value of a cookie as a longstring.

$Web_Get_Cookie_Lstr takes two arguments and returns a longstring or null for any error condition.

Syntax

%string = $Web_Get_Cookie_Lstr( name, occurrence )

Syntax terms

name	The name of the cookie, returned by $Web_Cookie_Name. Required argument if occurrence is not specified, otherwise optional.
occurrence	The occurrence number of a cookie, or the occurrence number of the cookie matching name, if name is specified. Optional argument if name is specified, otherwise it is required.

Usage notes

• $Web_Get_Cookie_Lstr returns the value of a cookie sent by the browser and is not affected by $Web_Set_Cookie or $Web_Set_Cookie_Lstr calls before the $Web_Get_Cookie_Lstr call. For example, if a browser sent a cookie called "FOO" with a value of "PUB", in the following code

  %RC = $Web_Set_Cookie( 'FOO', 'BAR') %FOO = $Web_Get_Cookie_Lstr( 'FOO' )

  %FOO would be set to "PUB".

• $Web_Get_Cookie_Lstr works pretty much like $Web_Get_Cookie or $Web_Cookie_Parm except
  • It can return more than 255 bytes of data into a longstring.
  • It causes request cancellation if the result would be truncated on assignment to the 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 each cookie into a User Language LONGSTRING variable of the same name.

%DESC = $Web_Get_Cookie_Lstr( 'DESC' ) %INFO = $Web_Get_Cookie_Lstr( 'INFO' )
