Hello, I've just came from ByetHost, they have a CPU limit in place. Is there such a thing here, limiting the amount of total runtime of scripts (besides the 30 sec PHP script runtime) or a limit on CPU resources? Also, I see that the cron only allows two runs per day, I need a script to run about 4 times a day, to manage some of my stuff. Would a free web based cron service be against the TOS? Can I just go to http://mywebcron.com/ and set the script to run once every 6 hours? Also, does HelioHost check the User Agent parameter of the connections? Some of my cURL connections do not specify that, and that got me into a message with ByetHost. Thanks in advance for all help.
