lhowlong=len(pcook)
lwhereis=instr(document.cookie,pcook)
if lwhereis=0 then
cookievalue=false
else
lstartpos=len(document.cookie)-lwhereis-lhowlong
lstartstring=right(document.cookie,lstartpos)
do
lchar=left(lstartstring,1)
if lchar=";" then
   cookievalue=lendstring
    exit do
  else
  lendstring=lendstring & lchar
  if len(lstartstring)=1 then
   cookievalue=lendstring
   exit do
  else
  lstartstring=right(lstartstring,len(lstartstring)-1)
