I have two sites on different dedicated servers and am passing visitors from one to another, based on specific actions.  To do this, I use Header("Location:  http://www.foo.com"); and successfully redirect the majority of users.  However, anywhere from 5-30% of traffic never makes it to the other site, according to the apache logs on each.  I'm unable to duplicate the problem, as it seems to only happen under a real life load (moderate, though, not heavy), but I have visitors who show up in the logs for box 1 and not box 2.  I added a Try {} Catch {} block to the header redirect, to collect more useful troubleshooting details, but I never got a single alert, suggesting the php redirect was successful.

Does anyone know why this would happen and/or what's happening and/or how to set up a good test to trace visitors from one site to another?

Sorry if this is stating the obvious... but do you call "exit;" right after your header() call?
