Hi everybody,
I'm making a nice little webapp in Catalyst: metheorology models run via
crontab and catalyst shows the data and graphs that they produce. Im very
happy how it's working so far.
Now I have been asked if I could make a "Run the model now" button, that
would run a script (the model) and show it's output in a popup window.
The process may run for about 15 minutes, so I have to handle , somehow,
the browser timing out because of lack of output. I thought about making the
script output to a tmp file and using ajax to query that file.
What is the best way to do that? Is there a nice, magical CPAN module out
there? :)
You don't really need one..
Simplest way to handle this would be for the web page to kick off the
model running in another process, and then immediately display a web
page that says "Please wait, model running.."
That page then either uses javascript or a http-refresh mechanism to
check back every 30 seconds to see if the model is ready yet.
