is mod_disk_cache.c compiled into mod_cache.so? Nope :)
AP_MODULE_DECLARE_DATA is a funky one-off entity that's perfect for this...
it is an "always export" declaration. Lousy for adding to a .h file (you need
to give the module it's own macro set, see mod_dav for one example), but it's
just perfect for exported private data, such as...
module AP_MODULE_DECLARE_DATA isapi_module = {
STANDARD20_MODULE_STUFF,
create_isapi_dir_config, /* create per-dir config */
merge_isapi_dir_configs, /* merge per-dir config */
NULL, /* server config */
NULL, /* merge server config */
isapi_cmds, /* command apr_table_t */
isapi_hooks /* register hooks */
};
