Daniel, I believe (I am a module programmer with only novice Apache API experience) that there are quite a few server configs created.
From my experiments with my module, there appear to be at least two running all the time (what appears to be a "global" server config and one server config for every virtualhost defined in httpd.conf and other config files). Also, I would guess that each child process has their own copy of the server configs. I believe this because every time a server_config_merge function is called, the server config is edited. The server_config_merge function is run at server startup (based on httpd.conf settings) and again at the beginning of a request (when .htaccess files are parsed... although I am not sure why). AFAIK, every time a "variable" in the parent process is written to by a child process, the child process is given a copy of the parent's variable and only that copy (in the child process) is edited. By that logic, I would think that not only do you potentially get one server_config struct per (child process which writes to the server config), but each server_config_struct is independently modified by each child process (on potentially different). Maybe this page can shed some light on your questions: http://www.fmc-modeling.org/projects/apache/html/3_3Extending_Apache.html Regards, Dave -- David Wortham Senior Web Applications Developer Unspam Technologies, Inc. 1901 Prospector Dr. #30 Park City, UT 84060 (435) 513-0672 On 3/22/07, Danie Qian <[EMAIL PROTECTED]> wrote:

Thanks for replying. Does every child process has one copy of the server config or is there only one copy in the whole server memory space? I dont want every child to have a copy as the config data is quite big in my case. Best Regards, Daniel
