browser resends ajax request?

I have a web app that updates a very large file. processing time takes around 45 seconds (and this is good. there might be ways to trim that down, but it is seriously a huge file). I use (old-school) ajax (not jquery) to call a web service that runs through the file, it checks for errors and updates a database. everything seems to be working EXCEPT that the browser keeps re-sending the ajax request every 30 seconds if it doesn't get a response. and my web server just starts a new thread each time.

Is this a behavior I can change or prevent?

well - apparently this can happen under some circumstances like here:

or

for me it seems that retrys can be valid behaviour thus i think somehow it should be handled by the software - in case the performance cant be improved to avoid the timeouts.
