PHP: reasons to use GET and POST request at the same time?

it fixes the issue Because GET and POST do not have the same semantic value. GET requests should be generally safe to perform at any time without compromising the system, while POST requests should be used when doing something important (like accepting a monetary transaction, or, in a less dramatic way, post a comment or something like that).
So it might make sense to make a POST request through AJAX if its result will affect a system.

wish of those help For many processes I expect wall clock time to greatly exceed total CPU time. Few processes are CPU bound so they will spend a lot of time waiting. Fortunately wait times don't get charged to the process anymore. Things that cause waits:
I/O of any sort (disk, network, interprocess pipes, etc.). Resource synchronization between processes. Time slices allocated to other processes. Memory swapping (not to common these days). Interrupts of pretty well any other sort.

time bash -c "read ans"

seems to work fine It looks like you are submitting the form and the ajax request. Try adding the following to prevent the default submit action (GET).

.submit(function(e) {
  e.preventDefault();
  //ajax code
}

Hope that helps The idea is that the firewall is up before any network traffic can happen on a certain interface or all interfaces and that the firewall is up as long as networking is possible, meaning as long as the interface(s) is up.

I hope this helps you . I'm trying to do a post request to an external server using the Request - Simplified HTTP client in node.js. I expect to get the departure times of a specific bus station. But everytime I get a bad response from the server (status code 500). The code I'm using is listed below: , I ran the code and get the following error:

Error: Cannot find module 'request'

headers: {  'accept': '*/*',
            'user-agent':'*' }
