Ajax Post & IE8
I have an Ajax script that runs on IE9 & FF but not IE8...well it runs but there is some sort of memory leak so the script runs slower and slower with each consecutive click because the code being processed is not being cleared each time, or something. I found some articles online and tried them but with no luck. How do I stop the cycle?

Code:
 if (window.XMLHttpRequest){xmlhttp=new XMLHttpRequest(); }
        // code for IE
        else if (window.ActiveXObject){xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); }
        if (xmlhttp!=null){
            
            $.ajax({type: "POST", url:"/load-content/", global: false, data:({img:showcase, clicked:click_name, off:off_name,menuv:aname}), async:true, dataType: "html", success: function(xml) {
                   // format and output result  
               
                   nshow = jQuery("div p.p2").html(xml);
                
            xmlhttp= null;
            }
        });

        return false;
        }

SAFE_ASTERISK(8)					     Linux Programmer's Manual						  SAFE_ASTERISK(8)

NAME

       safe_asterisk -- A wrapper to run the asterisk executable in a loop

SYNOPSIS

       safe_asterisk [ asterisk_params ]

DESCRIPTION

       safe_asterisk is a script that runs asterisk in a loop, which can be useful if you fear asterisk may crash.

       The  script  does  not run in the background like a standard service. Rather, it runs in its own linux virtual console (9, by default).	It
       also uses the option '-c' of asterisk(8) to avoid detaching asterisk from that terminal.

       safe_asterisk also runs asterisk with unlimited core file size, and thus asterisk will dump core in case of a crash.

       To get a "picture" of console 9, from another terminal (e.g: from a remote shell session) you can use:

	 screendump 9

       The init script of the Debian package should be able to run safe_asterisk as the  asterisk  service,  if  so  configured.  See  coments	in
       /etc/default/asterisk

FILES

       /tmp
	      safe_asterisk runs in that directory, rather than in / as usual.

       /tmp/core
	      If core files were generated there, they may be

       /etc/asterisk/startup.d
	      Files  in  this directory will be 'source'd by the safe_asterisk script before it starts Asterisk proper, allowing them to set addi-
	      tional environment variables or run any other steps that are needed for your system.

BUGS

       While showing the output on a console is useful, using screen(1) as the terminal may be better.

       The script does not read configuration from standard location under /etc

       It uses fixed locations under /tmp , and thus may be exposed to a symlink attacks.
