I have an unusual problem. I have a script that takes a little while to run, creating a PDF. Unfortunately, it is running on a webfarm with a load balancer in front of it that likes to think that the server is dead if it gets no response for some time. I have found that if I flush the headers back to it, the load balancer will wait for as long as need be after that. My problem is I can't flush the headers withOUT sending any data (right now I can just do an echo " "; flush(); and it sends the headers) but I want to force the headers to output while still not outputting any actual data. Is this possible?
