RewriteEngine on
RewriteRule ^([^./]{3}[^.]*)$ /index.php?page=$1 [QSA,L]

Why it does not work after i request http://localhost/webme/test

Sometimes on localhost Physical root folder is c:AppServwwwWebME The script is held in .htaccess within the root folder

It ought to be redirect to http://localhost/webme/index.php?page=test

Your rewrite is altering /webme/test to /index.php?page=test. Now you ask , in case your .htaccess file is within "/webme/" or perhaps in the document root ("/").

In case your document root is within c:\AppServ\www\ as well as your .htaccess file is incorporated in the webme directory, you have to include "webme" within the target:

RewriteRule ^([^./]{3}[^.]*)$ /webme/index.php?page=$1 [QSA,L]

OR by getting rid of the key slash inside your target

RewriteRule ^([^./]{3}[^.]*)$ index.php?page=$1 [QSA,L]

Otherwise, in case your .htaccess is incorporated in the document root ("/") you will want to complement against it:

RewriteRule ^webme/([^./]{3}[^.]*)$ /webme/index.php?page=$1 [QSA,L,NC]
