It's actually very simple! ! Add
AllowOverride All #Allow all commands
AuthName "member" #Authentication information
AuthType Basic #Authentication category
AuthUserFile d:/down/ww.pwd #Authentication password file Path
require user askswin #The user who can enter askswin
It turned out that the reason why it never worked was that the path c:/apache/htdocs/down did not use an absolute path! ! So it keeps failing! ! Moreover, various documentation files are specific to UNIX. Does the UNIX path use a drive letter? So it has never been successful! !
