You post data through HTTP POST, and don't process it until after proper validation.[/quote]

thanks for the post/response. here's another question then. i have a script that is going to be running on a box and will need to send data to my page every couple of minutes.
in my old version, i just had the script use a url like:

http://myserver/mysite/?var1=123&var2=123 etc.

i guess i'll have to see if i can do a http post from the script....
as far as the web page is concerned then, i would just code it as if i had a form, and the form was posted... is this correct?[/quote]

Yes, just like a form. Checking $this->input->post('varname', TRUE);

You can use Curl to POST to pages, so if it is a shell script you can deal with the change in method fairly easily.

Here is one example of why you should not change data on a GET, only POST

If you want to get plucky and more advanced on how you handle events like your update, Phil Sturgeon made a couple nice libraries for CI,

For example, I have a mail server application running on a host that handles sending all the emails out for all my domains, and each domain sends the emails to the central server with a rest PUT command.
