Apache Reference Manual (2)_PHP教程

AuthName directive
Syntax: AuthName auth-domain
Context: directory, .htaccess
Override: AuthConfig
Status: core
This directive sets the name of the authorization realm for a directory. This realm is given to the client so that the user knows which username and password to send. AuthName takes a single argument; if the realm name contains spaces, it must be enclosed in quotation marks. It must be accompanied by AuthType and require directives, and directives such as AuthUserFile and AuthGroupFile to work.

AuthType directive
Syntax: AuthType type
Context: directory, .htaccess
Override: AuthConfig
Status: core
This directive selects the type of user authentication for a directory. Only Basic and Digest are currently implemented. It must be accompanied by AuthName and require directives, and directives such as AuthUserFile and AuthGroupFile to work.
--------------------------------------------------------------------------------
BindAddress directive
Syntax: BindAddress saddr
Default: BindAddress *
Context: server config
Status: core
A Unix® http server can either listen for connections to every IP address of the server machine, or just one IP address of the server machine. Saddr can be
*
An IP address
A fully-qualified Internet domain name
If the value is *, then the server will listen for connections on every IP address, otherwise it will only listen on the IP address specified.
Only one BindAddress directive can be used. For more control over which address and ports Apache listens to, use the Listen directive instead of BindAddress.
BindAddress can be used as an alternative method for supporting virtual hosts using multiple independent servers, instead of using sections.
