Per-Server Configuration

Since a single instance of Apache may be called on to handle a request for any of the configured virtual hosts (or the main host), a structure is defined that holds the information related to each host. This structure, server_rec , is defined in httpd.h:

struct server_rec { server_rec *next; /* Description of where the definition came from */ const char *defn_name; unsigned defn_line_number; /* Full locations of server config info */ char *srm_confname; char *access_confname; /* Contact information */ char *server_admin; char *server_hostname; unsigned short port; /* For redirects, etc. */ /* Log files --- note that transfer log is now in the modules... */ char *error_fname; FILE *error_log; int loglevel; /* Module-specific configuration for server, and defaults... */ int is_virtual; /* True if this is the virtual server */ void *module_config; /* Config vector containing pointers to * modules' per-server config structures. */ void *lookup_defaults; /* MIME type info, etc., before we start * checking per-directory info. */ /* Transaction handling */ server_addr_rec *addrs; int timeout; /* Timeout, in seconds, before we give up */ int keep_alive_timeout; /* Seconds we'll wait for another request */ int keep_alive_max; /* Maximum requests per connection */ int keep_alive; /* Maximum requests per connection */ int send_buffer_size; /* Size of TCP send buffer (in bytes) */ char *path; /* Pathname for ServerPath */ int pathlen; /* Length of path */ char ...
