[jQuery] timer and .post

I have an ap built on the portable application here: http://portablewebap.com/ I also use the timer plugin and have a .post function that saves for data every 1/2 second. On some computers I get errors of timing out. Is this because it is running my php file too frequently? Thanks for the help.

[jQuery] .post

Sorry for the noob question. I am using the .post ajax method on a form. I use the following jquery code: $("form#changeinfo").submit(function(){ $.post("ownerdetails.php", { name: $("#name").val() }); }); So when the form with the id of changeinfo is submitted it posts information to ownerdetai
