Code:
change to  this:
on *:text:!sabdetails*:*: {
 [color:red]set %un  $2[/color]
 sockopen bot 192.168.1.2 6080
} 
[color:blue]
remove this completely
;on *:sockopen:bot: { 
;  sockwrite -n $sockname GET $+(/s3h/getdetails.php?name=,%un)
;  sockwrite -n $sockname Host: $+(192.168.1.2,$crlf,$crlf)
;} [/color]

on *:sockopen:bot: { 
  sockwrite -n bot GET http://192.168.1.2:6080/s3h/getdetails.php?name=[color:red] $+ %un [/color]
} 
on 1:sockread:bot: {
  if ($sockerr > 0) return
  :nextread
  sockread %bot
  if ($sockbr == 0) return
  if (%bot == $null) %bot = -
