How does ip/~username work in server

How does ip/~username point to public_html instead of /home/username in server.
Solution : Its done by “UserDir”
httpd.conf might have an entry as below :
=================
root@server [~]# grep UserDir /usr/local/apache/conf/httpd.conf UserDir public_html root@server [~]#
=========================
Thats what is specifying the document root.
By default "UserDir" is enabled.
To disable we can use :
UserDir disabled user4 user5 user6http://httpd.apache.org/docs/2.0/mod/mod_userdir.html
scp and rsync timestamp
ARUN Post in GENERAL RULES, RSYNC，

2011
When a file is scp to a remote server, the time stamp of the file in remote server will be changed and hence the file will be created with new date and time.
When we rsync a file or a folder, time stamp will also be copied to new server.
ie. when a file created on jan 1st is moved to a remote server using rsync, then the remote server will show Jan 1st as the file creation date and not the new date.
