Firefox Ajax xmlhttp.open problem

howdy experts...

I have run into an issue with Firefox browser and an Ajax call.
xmlhttp.open("GET",url1,true)
vs
xmlhttp.open("GET",url1,false)

i wanted to have the function run with the async status false but it appears that Firefox will not run it (Works in IE and Safari). Does Firefox have a problem with the setting false? seems to run if set to true but because I have a number of things going on in the page setting false seems to work better...

thanks

ajax is a bit "funny" when running under the "file:" protocol (ie your test page is running on the local file system). make sure you run your test page on a webserver...

yup all files are located on a server and in the same folder
all files have the same .asp extension

thanks

thanks kiranvj....

"But Firefox does not fire onreadystatechange events in that case so
you need to put your code processing the response after the send call"

not exactly sure what is ment by this line...

if my code is like so:

xmlhttp.onreadystatechange=loadList1;
xmlhttp.open("GET",url1,false);
xmlhttp.send(null);

have a suggestion to make it fire?
the code runs much much smoother set to false but i guess i could check for firefox and set to true just for that browser? any other suggestion?

thanks
