[ale] OT: XMLHTTP + IE

[cfowler]

I should try this code instead.  What was strange is that I woke up this
morning and on my screen I was still tailing the apache access_log.  I
noticed that IS tried to access the alarm_check.pl CGI
66.23.198.138 - - [14/Dec/2006:22:37:50 -0500] "GET /SC/Test/alarm.pl
HTTP/1.1" 200 295 
66.23.198.138 - - [14/Dec/2006:22:37:51 -0500] "GET /SC/Test/Alarm.js
HTTP/1.1" 200 867
66.23.224.81 - - [15/Dec/2006:06:03:17 -0500]
"GET /SC/Test/alarm_check.pl HTTP/1.1" 200 51

Last night at 22:37 I did a refresh in IE.  The req.open() code did not
call alarm_check.pl until 06:03 this morning.  Very strange...
