XmlHttprequest and perisistent connections

[Wilco]

I'm having trouble with an AJAX script which polls an XML file off a
webserver. Problem is that for every XMLHttpReqeust I make, a new TCP
connection is set up (which eats a lot of resources from my embedded
device). Is this normal behaviour?

The HTTP server supports HTTP 1.1, so I suppose it should use a
perisistent connection. I checked if the webserver was configured
properly, and it is.

I did some research on the subject and looked at the wireshark output
of a Mozilla firefox 3.0 quick search bar search (which also uses
XmlHttpRequest). The requests in this log are done via a single TCP
connection. I compared the source js to my own js but there where no
functional differences.

Also checked websites as http://ajaxref.com/ http://ajaxpatterns.org/
and http://radio.javaranch.com/pascarello/2006/03/30/1143735438047.html
but could not find any info.

Anyone got a clue?

if is not your code, maybe is your data... your URL parameter, like

http://www.mysite.com/foo/bar/caa/zeta
vs
?data=newdata&json=()

maybe the god's of software are mad at you for use the wrong type.

What I did in the past is opend a connection, wait for a response then close
the connection(delete the object).
This is much different than when it is run under IE. Firefox doesnt like to
make multiple requests.
My application was a remote appliance that used ajax to get display data. It
was a PIC running Mchips stack.
I used the default socket count.

Hope that helps.
