keeping a page cached?

**MrCoolDale** · September 14th, 2004, 3:07 AM

I need some help.
First, is it pronounced like cash or cashay? I hear it both ways and wasn't sure which was was correct, if either.

second. I need some code from ya'll. I need something to keep a page cached for a while, about an hour would be nice. I'm making a site that will have a lot of static content (header, footer, navigation, various images, etc.) and the rest is phpinclude().

I would prefer to have a shell for an index page. I want just index.html to have very little in the source, makes things easier on me. I would use phpinclude() or header() or whatever else for everything.

Any help here is much appreciated. If this is already a thread somewhere, feel free to yell at me, but I didn't see it. Thanks in advanced.

I don't think you can force a browser to cache a page, but only force it to not read from cache. It should happen automatically by the browser, unless your site tells it not to, or the user has disabled it.

I could be completely wrong, though. I spent a couple of minutes searching on Google, and found nothing on how to force a browser to cache a page.

A hiding place used especially for storing provisions.

PROVISIONS.

I use php include for a lot of stuff. My index.php looks something like this:

PHP Code:


			
<?php

require 'head.inc';

if (isset($_GET['class'])) {

$class="";    

}

if (!isset($_GET['page'])) {$content= 'page1.inc';}

else {$content= $_GET['page'].'.inc'; $class="tc";}

include 'containers.inc';





include $content;

include 'footer.inc';

?>

The 'class' variable is passed with the ? in the url and sets the main page.

The page is designed with CSS and divs.

If you use CSS, and much of your graphic content is part of that css (backgrounds to divs, etc) then you'll see a lot of that get cached so that it won't have to be reloaded.

Cache is a worthy foe.

Different browsers implement cache and provide for many possible configurations.

For instance - IE5-6 allows for settings that will force the browser to fetch for a new instance of the page contents on every visit to a site. Or it can be set to never. These settings work, sort of - because they can be overriden if you output the right magic headers for the browser.

As Gump says - "browser cache is like a box of chocolates. you never know what you gonna get. Jenn-ay! Come back to Greenboro!"

thanks everyone, I have another question for bigjohn.

John - how does that coding work? What kind of stuff would I need to change if I wanted to include a page called header.html? I'm still kind of new to php and don't really know what I'm looking at.

**Bigjohn** · September 14th, 2004, 2:38 PM

you can 'include' any filename. You just have to make sure that you don't include a </body> before proper content...

Here is a head.inc:

PHP Code:


			
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"

"http://www.w3.org/TR/REC-html40/loose.dtd">

<HTML>

<head>

<title>HOST-MY-SITE.COM - Welcome!  Value web-hosting and Discount Domains!</title>

<meta http-equiv="Content-Type"

content="text/html; charset=iso-8859-1" >

<link rel="stylesheet" type="text/css" href="css/menus.css" >

<script language="javascript" src="popwin.js" type="text/javascript">

</script>

<script language="javascript" src="checkform.js" type="text/javascript">

</script>

<script language="javascript" src="scriptmailer.js" type="text/javascript">

</script>



</head>

notice something? Not a tick of PHP code in there...

**MrCoolDale** · September 14th, 2004, 2:44 PM

to tell you the truth bigjohn, I haven't the slightest idea what I'm looking at there. What exactly does that script do?

- Dale?

**Bigjohn** · September 14th, 2004, 2:55 PM

The scripts don't do anything.

If you look at the index.php you'll see 'require head.inc'

that means that every instance of the page will load that. Because PHP is server parsed, the first bit of content that is returned to the client browser is the content in the head.inc file. Note that it's completely the same as if I did that part of the page in HTML alone, right?

How I learned to do this is:

1 - think of the page that you'd want and how it would be built in HTML
2 - think of the logical ways to break it into pieces so that you can update the content.

then hack the parts into '.inc' files.

if content has to be dynamic inside, you can use variables too...
