Sorry for the obscure subject, but english is not my language. Well, situation:
server side language: php In a page, i need to call an url (on another server) that start a process (creates a jar file assembling many other files). This call will be done via curl (it has been already written). If the result of this call is Ko, stop everything. If it is OK, I must call (let's name this call, second call) another url which output can be: 1) Error -> Stop everything 2) Wait, not finished 3) The file is ready If 1, ok I'll print out a message If 3 I'll print out a link to download the file If 2 I need to call again the url (and so on, until I get 1 or 3) I thought to use jheartbeat (http://www.ajtrichards.co.uk/heartbeat/) to make my 'second call' , but since I'm noob, I don't know how to make these 2 things: A) Launch heartbeat only if the result of the curl call is OK B) Evaluate the 'response' of the 'second call' and stop heartbeat if the response is 1 or 3 (then I'll append someway the message or the link). I think I could attach heartbeat to a button (visible only if the curl call response is OK) and trigger the onclick or onmouseover event, but I'd prefer having it starting automatically if the curl call response is OK. Any hint about both A and B? Thank you in advance, Paolo
