I suggest you launch apache with the config file as a parameter and retrieve the filename it via ps afterwards. Alternatively you can also start out with a clear architecture and put the config files in a predefined location, defined by the URL. Like /etc/apache/.../httpd.conf_www.example.com Then you run over all these files, extract the PIDfile, extract the PID from the file and see wether there are running processes at this PID. Be really careful when updating running apaches automatically. But I guess you know what you are doing. regs, Christian -----Ursprüngliche Nachricht----- Von: Vinay Purohit [mailto:Vinay.Purohit@xxxxxxxxxx] Gesendet: Dienstag, 8.
