using UserDir to redirect to local web page

first add to new line in the /etc/apache2/httpd.conf:

UserDir workspace/webPage

then if you type localhost/~liqi/test.html, this would display the web page in the /home/liqi/workspace/webPage/test.html.

now add the UserDir module to apache2

sudo a2enmod userdir

then restart apache2, it works!
