[jQuery] Ajax: how to choose between post, get or ajax() ??

[jQuery] Ajax: how to choose between post, get or ajax() ??


I need to silently update an xml file to store some user's usage
statistics, basically i pass an object to a php script, which
generates the xml and stores it in a file.
Now, looking at the ajax chapter of the docs, i'm not quite sure
what's the best method to do that:
$.get, $.post or $.ajax ?
I think $.post() is good enough for my need but i'd be very interested
to hear your opinion.
thanks!
