grantp22 Posted October 12, 2009 Share Posted October 12, 2009 Can anybody please explain to me why my php page keeps downloading the images and other items every single time the page is loaded or refreshed. I would have thought that the images get cached and re-used without having to download the images etc, all the time, over and over! This happens everytime the page needs to load or refresh, is there something wrong with my code layout that is causing this or is it my html header that is the problem or is it something else all together? This is eating through my bandwidth and will do the same for potential users of my site, not a very good first impression entering my site. If somebody can help me solve this, I will be so greatful! Here is my test page code: <?php /** * ForgotPass.php */ include("include/session.php"); ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3c.org/TR/1999/REC-html401-19991224/loose.dtd"> <HTML lang=en xml:lang="en" xmlns="http://www.w3.org/1999/xhtml"> <head> <meta name="generator" content="Microsoft FrontPage 4.0" /> <title>Forgot your password?</title> <meta content= "This is just a test page." name= "description" /> <meta content="test, test page, online test" name="keywords" /> <link href="favicon.ico" rel="SHORTCUT ICON" /> <meta http-equiv="Content-Type" content="text/html;

pastcow Posted October 12, 2009 Share Posted October 12, 2009 Its probably nothing to do with your code and more to do with your server settings. Get the YSlow plugin or the pagespeed plugin for firefox, run it on your website and see what it complains about. It should come up with a set of suggestions for speeding up your page Link to comment https://forums.phpfreaks.com/topic/177474-why-does-my-php-page-download-images-over-and-over/#findComment-935764 Share on other sites More sharing options...
grantp22 Posted October 12, 2009 Author Share Posted October 12, 2009 So you say it's nothing to do with my code? Does it look ok to you, it looks ok to me!

pastcow Posted October 12, 2009 Share Posted October 12, 2009 You've used tables for design when CSS would probably be much neater and you could cut down the number of images by using css-sprites for the corners.. theres lots that can be done to the code but I think the issue your having is mainly with your server Link to comment https://forums.phpfreaks.com/topic/177474-why-does-my-php-page-download-images-over-and-over/#findComment-935818 Share on other sites More sharing options...

grantp22 Posted October 13, 2009 Author Share Posted October 13, 2009 I am testing on IE7 from my own system, and the website is hosted on a free webhost www.000webhost.com My browser settings are set to automatically check for newer versions of any webpage.

grantp22 Posted October 15, 2009 Author Share Posted October 15, 2009 Somebody provided me with a link http://www.mnot.net/cache_docs/ to an interesting document, here is a short extract as seen below, it seems to explain my problem in a nutshell or at least sounds like it could be the cause! Implementation Notes — Server-Side Scripting One thing to keep in mind is that it may be easier to set HTTP headers with your Web server rather than in the scripting language. Try both. Because the emphasis in server-side scripting is on dynamic content, it doesn’t make for very cacheable pages, even when the content could be cached. If your content changes often, but not on every page hit, consider setting a Cache-Control: max-age header; most users access pages again in a relatively short period of time. For instance, when users hit the ‘back’ button, if there isn’t any validator or freshness information available, they’ll have to wait until the page is re-downloaded from the server to see it. ---------------------------------------------------------------- The problem I have is that I don't want some content to be cached, because the content ie: graphics will change roughly once a week with php loading image paths from a mysql database everytime the page is loaded, there are no static image paths for some content that I want to be dynamic, so php echo's the image source paths when the page is loaded. But there "is" content that I DO want to cache, which never changes, and they have hardcoded image source paths and at the moment these images are downloading over and over. How can I go about allowing some images to be cached (static <img src="http://www.mysite.com/img/image1.jpg" is my hardcoded path) and (dynamic <img src="<?php echo $req_image_info['image1']; ?>" are echoed database values). This works perfectly with the exception of all images being downloaded over and over, and not seeming to be cached at all. Any guidance on this issue will be very much appreciated Thanks Grant Link to comment https://forums.phpfreaks.com/topic/177474-why-does-my-php-page-download-images-over-and-over/#findComment-937320 Share on other sites More sharing options...
redarrow Posted October 15, 2009 Share Posted October 15, 2009 There nothing on the page you provided, to force image downloads, so it not that page? Your problem is from a included page.
