If you use name based vhosting, there isn't really a limit (beyond memory of your machine etc). <quote> Why can't I run more than <n> virtual hosts? You are probably running into resource limitations in your operating system. The most common limitation is the per-process limit on file descriptors, which is almost always the cause of problems seen when adding virtual hosts. Apache often does not give an intuitive error message because it is normally some library routine (such as gethostbyname()) which needs file descriptors and doesn't complain intelligibly when it can't get them. <end quote> So the limit mentioned on Apache's site is more of a limit of the number of IPs you can bind to any one interface (and the number of per-process file descriptors you have).. It's not really a limit of Apache itself. We're approaching that number (255) on one of our Linux boxes, however we use name based vhosting, so it's only one IP we're dealing with. - Mitch ----- Original Message ----- From: Lester A.
