Hi Daniel,


the server_rec doesnt have a pool field. which field can I use to store
the
data?



AFAIK, server config is not the same as server_rec.

You create server configuration as in the following:

<code>
typedef struct {
   /*
    what ever data you need in server config
    .
    .
   */
} my_cfg;

static void *my_server_config_create(apr_pool_t *p, server_rec *s) {
   my_cfg *cfg = (my_cfg *)apr_palloc(p, sizeof(my_cfg));
   /*
   Set your configuration in cfg struct
   .
   .
   */
   return (void *)cfg;
}

module AP_MODULE_DECLARE_DATA my_module = {
   STANDARD20_MODULE_STUFF,
   NULL, /*per-dir create,*/
   NULL, /*per-dir merge,*/
   my_server_config_create, /*per-sever create*/
   NULL, /*per-sever merge*/
   cmds,
   reg_hooks
};
</code>

now you can retrieve your server configuration as follows, when you have a
pointer to a request, 'r':

<code>
my_cfg *svr_cfg = (my_cfg *)ap_get_module_config(r->server->module_config,
&my_module);
</code>

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.
