URI Functions

Some of these functions use the uri_components structure:

typedef struct {
    char *scheme;     /* scheme ("http"/"ftp"/...) */
    char *hostinfo;   /* combined [user[:password]@]host[:port] */
    char *user;       /* username, as in http://user:passwd@host:port/ */
    char *password;   /* password, as in http://user:passwd@host:port/ */
    char *hostname;   /* hostname from URI (or from Host: header) */
    char *port_str;   /* port string (integer representation is in "port") */
    char *path;       /* The request path (or "/" if only scheme://host was 
                      /* given) */
    char *query;      /* Everything after a '?' in the path, if present */
    char *fragment;   /* Trailing "#fragment" string, if present */
    struct hostent *hostent;
    unsigned short port;	
                      /* The port number, numeric, valid only if
                      /* port_str != NULL */

    unsigned is_initialized:1;
    unsigned dns_looked_up:1;
    unsigned dns_resolved:1;
} uri_components;
