How to change Joomla Admin Folder Name or Path

how to protect your admin side of website. Rename Joomla administrator directory without having to modify any Joomla code.

1. Create a new directory in your root directory (eg. "newadmin")
2. Create an index.php file in your "newadmin" directory

## newadmin/index.php

$admin_cookie_code="1234567890";
setcookie("JoomlaAdminSession",$admin_cookie_code,0,"/");
header("Location: ../administrator/index.php");

3. Add this to the beginning of index.php in real administrator folder

if ($_COOKIE['JoomlaAdminSession'] != "1234567890")
{
header("Location: ../index.php");
}

To login Joomla administration page, go to "http://yoursite.com/newadmin/". The php code will set a cookie that expires at the end of the session and redirect you to your real administration page. No one will be able to load anything from the administrator directory without having gone through the "newadmin" directory first.

Load Flash Video Before Load Front Page Joomla

Create a .htaccess file which contains the following code:

DirectoryIndex index.html index.php

Then create a index.html where you include the flash. If you make the flash linkable and have it go to the index.php it should work.

web page is not cached, across all browsers

set of headers which works in all of the mentioned browsers is the following:

Cache-Control: no-cache, no-store, must-revalidate
Pragma: no-cache
Expires: 0

The PHP way would look like:

header('Cache-Control: no-cache, no-store, must-revalidate'); // HTTP 1.1.
header('Pragma: no-cache'); // HTTP 1.0.
header('Expires: 0'); // Proxies.

The Java/Servlet way would look like:

response.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
response.setHeader("Pragma", "no-cache"); // HTTP 1.0.
response.setDateHeader("Expires", 0); // Proxies.

The ASP.NET way would look like:

Response.AppendHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.0.
Response.AppendHeader("Expires", "0"); // Proxies.

The plain HTML way would look lile:

The Cache-Control is per the HTTP 1.1 spec for clients (and implicitly required by some browsers next to Expires),
the Pragma is per the HTTP 1.0 spec for clients and proxies and Expires is per the HTTP 1.1 spec for clients and proxies. Other Cache-Control parameters are irrelevant if the abovementioned three are specified. The Last-Modified header is only intersting if you actually want to cache the request.

Change suffix from html to htm in Joomla

Goto includes/router.php
Line 57 : Replace the current code there with ,

if($suffix = pathinfo($path, PATHINFO_EXTENSION))
{
$path = str_replace('.'.$suffix, '', $path);
$vars['format'] = $suffix;
if ($suffix == 'htm')
{
$path = str_replace('.'.$suffix, '', $path); //pair of single quotes inserted
$vars['format'] = 'html';
} else {
$path = str_replace('.'.$suffix, '', $path); //pair of single quotes inserted
$vars['format'] = $suffix;
}
}

Then goto line 101 : Replace the current code there with ,

if($format = $uri->getVar('format', 'html'))
{
$route .= '.htm';
$uri->delVar('format');
}

If you need the suffix to change from .html to .php , then just replace the .htm in the above code by .php and thats it..

if you are still not able to do it, then just download this ,
router.php file and upload it to includes folder.
