Cron With $_SERVER[REMOTE_ADDR] And $_SERVER[SERVER_ADDR]Mar 28, 2011
I'm on HostMonster and I'm trying to setup cron to play nicely with a Drupal install I have running and I'm running into problems trying to code for a condition that says, "IF I'm the server and I'm making the request to do CRON, then do the following..."Basically (in layman's terms), I'm having a hard time trying to figure out how I should code for cron requests from the server, which brings me to the following questions:1.) Do cron jobs always execute from the host server? For example, if $_SERVER[SERVER_ADDR] is always "220.127.116.11", does this mean that the 583 bytes sent for cron jobs always come from the same IP address or are there exceptions to this? The reason I ask this is because I have a poor man's byte counter in this cron code I'm working with that sets up a file read and keeps you in the reading loop until the byte count reaches 583 (which, according to my IP logs, is the number of bytes sent with each cron "ping" that gets made.) The code isn't firing, however, because I'm having a hard time making the code run from either cron requests or else from an inconsistency between the IP comparison code I have.2.) Before any cron code gets executed, I have "ignore_user_abort(true);" called at the beginning of the page. Will this effectively process all proceeding code thereafter if cron pings the page? In other words, will using this make the page get processed as if someone traveled to the cron.php page in their browser?
