cloning drupal sites to create new ones

I have tried more than 10 times but not working. You can test yourself.

Hello Ryan,

I will check out the link you sent; I don't have anymore questions right now regarding the duplication of a drupal site to reuse as a new and different site. But I do have 2 other questions on another subject if you don't mind.

1) I have recently installed the Ad module for running ad banners on the side bar area of my site
and from time to time I get this message: "ad module cache has been flushed to the database" which
visitors can also see. Is there a way to prevent this that you know of?

2) I have been wondering how to link a external javascript.js file to content in my drupal pages since there are no "head tags" available to paste the code into. I ran across a paragraph in the "Drupal 6 JavaScript and jQuery" book review that offered this solution:

"Second, the code can be loaded separately from the rest of the HTML. Again, this is usually done using the and tags. However, instead of putting the code between the tags, we use the src attribute to instruct the browser to retrieve an additional document from the server."

In this example, src="some/script.js" points the browser to an additional script file stored on the same server as the HTML document in which this script tag is embedded. So, if the HTML is located at http://example.com/index.html, the browser will request the script file using the URL http://example.com/some/script.js.

I tried this on one section code and it worked fine; but I tried it on several other occasions and it would not work.

Is there a tried and true way to link external javascript.js files to page content without getting too complicated?

If you have answers I would greatly appreciate your sharing the knowledge.

Thanks,
Edward

Dear Ryan,

I need the multisite feature as of my client so I did below(two way):
Sorry if I am bothering you and others.

Let me clear it:

I have one drupal database say "abc"
I have created another database in same machine say "xyz" and have imported
"abc" drupal sites dump into xyz 's database through phpmyadmin (no problem occured).
So we have two database in one machine: one is "abc" and another is "xyz" with same table structure.
My first abc databse url is: http://ipdaress/abc
and my newly imported databse url (might be) is http://ipdaress/xyz
(Here noted that I am using xampp, mysql in windows 2003 machine.)

FIRST WAY:
I havent changed any folders, passwords anything inside sites directory or in database or anywhere.
Only one change is in my settings.php file(under sites\default) I just added below lines:

$db_url = 'mysqli://root:password@localhost/xyz';

So the the total lines are below:

$db_url = 'mysqli://root:password@localhost/abc'; (previous ones whic autimatically written when I did setup abc drupal site)
$db_url = 'mysqli://root:password@localhost/xyz'; (I just copy pest and change the abc to xyz)
$db_prefix = '';

The directory structure is like below under sites:
sites
--- all
------modules
------themes
---default
------files
------default.settings.php
------settings.php

Now when in internet explorer I put http://ipdaress/abc its OK working.
but when I put http://ipdaress/xyz
I am now getting below message:

Object not found!
The requested URL was not found on this server. If you entered the URL manually please check your spelling and try again.
If you think this is a server error, please contact the webmaster.
Error 404
IPADDRESS
11/13/09 11:18:32
Apache/2.2.9 (Win32) DAV/2 mod_ssl/2.2.9 OpenSSL/0.9.8h mod_autoindex_color PHP/5.2

SECOND WAY:

AFTER READING THE ARTICLES WHAT YOU HAVE PROVIDED, I HAVE CREATED TWO FOLDERS INSIDE SITES DIRECTORY, ONE THAT ALREADY HAS ABC/DEFAULT AND NEW MANUALLY COPYING DEFAULT DIRECTORY AND RENAMED IT TO "XYZ":
SO THE DIRECTORY STRUCTURES ARE LIKE BELOW:

sites
--- all
------modules
------themes
---default
------files
------default.settings.php
------settings.php
---XYZ
------files
------default.settings.php
------settings.php

NOW AGAIN I HAVE CHANGED THE DB URL OF XYZ FOLDERS SETTINGS.PHP AND HIT THE URL TO MY BROWSER
$db_url = 'mysqli://root:password@localhost/xyz'; (I HAVE DELETED THE ABC DATABASE LINE)

SAME OBJECT NOT FOUND.

SO HOW CAN I GET WORK WITH SECOND URL(http://ipdaress/xyz) whats other steps I need to do?
(WHICH WILL SHARE SAME MODULE LIKE "ABC" WEBSITE?)
i HAVE TRIED AND READ MANY ARTICLES BUT COULDN'T GET WHERE IS MY PROBLEM.
I would be grateful to u if i get solution.Thanks many for your time.
