When I try to run the dev server, here's what I get: python manage.py runserver Validating models...

Wed, 13 Sep 2006 01:08:11 -0700 http://guruza.com/question/360/reward-5.00 My site spans ajax requests that take a while to execute on the server. However, this request becomes invalid if the user makes another request before the first one is completed. In order to save server resources, I'd like to be able to kill the 1st server request when the second one is sent. I was thinking about polling the session to see if a certain criteria is met. If it is, I'd just abort the current call. How would I do that? I guess I'd have to launch a second thread when the ajax request starts (on the server side) and that thread would poll the session every 100ms or so. If the criteria is met, it would kill the request. I'd like to see a code example of this. Wed, 30 Aug 2006 00:25:10 -0700 http://guruza.com/question/279/reward-10.00 I have a rails app that runs an nmap scan on a host and reports the response via ajax. I use backtick to run nmap via my controller. What I've noticed is that if the nmap scan takes a while (say about 2 minutes), rails will block all request until the shell command finishes executing. My question is if there is a more effecient way to run shell commands via rails? Will I have to thread the nmap scan so the rails controller doesn't block until it receives a response?
