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.

PHP Cron Jobs with cPanel

Cron jobs allow you to automate certain commands or scripts on your server to complete repetitive tasks automatically. A cron job allows you to run a certain command at times set by the job. For example, you could set a cron job to delete temporary files every week so that your disk space is not being used up by those files.

1. you can get started with the simple cron tool built into cPanel.url:

https://www.yoursite.com:2083/frontend/x/cron/simplecron.html?

To access the Cron Jobs Menu, click on the corresponding icon located on the main screen of your cPanel interface.

2. The cron email section of the Cron Jobs interface allows you to specify the email address where you would receive an email each time a cron job is ran for your account.

If you do not want an email to be sent for an individual cron job you can redirect the command's output to /dev/null like this:
mycommand >/dev/null 2>&1

You can enter the desired email address in the text box and click the Update Email button to apply the changes.

3. Next section of the Cron Job interface is where you actually set your cron jobs.
Once ready setting up the cron job click the "Add New Cron Job" button and it will be saved and activated for your account.

Want to select an option from all the select boxes. Remember to select an option in each box.

If you want something to run every day at 4AM:
select Minute: 0; Hour: 4; Day: Every; Month: Every; Weekday: Every;

4. The bottom part of the Cron Jobs interface will allow you to edit or delete existing cron jobs.

The command to run:
php -q /home/(username)/public_html/(scriptname).php
