How Can I Avoid "Page Has Expired" Warnings

2009-09-30T22:25:00.000-07:00

Most of the time many developer may face in this problem in may times. Might be they have already solved or not. Here i m pointing why is it happing and how to solve it.

The warning is a result of the user utilizing the browser's history mechanism to access a previously viewed page, usually by clicking the back button or refreshing. One cause of the warning is that the page has expired from the browser's cache.

PHP, by default, does not forbid caching. When you request a simple PHP script, no caching headers are returned. To solve this you can use two ways.

1) Edit php.ini file.

Set session.cache_limiter to PRIVATE by default it comes with nocache.

 session.cache_limiter = private

2) Edit through you PHP Code

      ini_set('session.cache_limiter', 'private');

Image Compression

2009-07-15T22:21:00.000-07:00

Nowadays it is common to work with images in programming language. Here I m putting some image compression function which can use in PHP. This is comes to common when developer working with image uploading and stuffz. Bcoz due to the storage matter we have to reduce images capacities to manage it.

It’s better to execute image compression PHP script in uploading page than ask user to do it.

Before using this script you have to enable GD library in your web server. And it’s better to enable EXIF library too when you are going to validate the image header files.

1 ) Script automatically compress the image base on the given dimension.
2 ) Automatically calculate the landscape image or portrait image.


function imageCompression($imgfile="",$thumbsize=0,$savePath=NULL) {

if($savePath==NULL) {
          header('Content-type: image/jpeg');
     }
 
     list($width,$height)=getimagesize($imgfile);
     $imgratio=$width/$height; 

     if($imgratio>1) {
          $newwidth = $thumbsize;
          $newheight = $thumbsize/$imgratio;
     } else {
          $newheight = $thumbsize;       
          $newwidth = $thumbsize*$imgratio;
     }
   
 // Making a new true color image
    $thumb=imagecreatetruecolor($newwidth,$newheight); 

 // Now it will create a new image from the source
     $source=imagecreatefromjpeg($imgfile); 

 // Copy and resize the image
 imagecopyresampled($thumb,$source,0,0,0,0,$newwidth,$newheight,$width,$height);  
     imagejpeg($thumb,$savePath,100);

    imagedestroy($thumb);
   
}

This imageCompression() you have to pass 3 parameter to execute.
// 1 - Source of your image file.
// 2 - Output image dimension.
// 3 - Destination path of the image.


imageCompression($uploadfile,250,$uploadfile);

How to make Firefox Faster

2008-07-07T04:20:00.001-07:00

Here is the way of doing it…

1. Type "about:config" into the address bar and hit enter. Scroll down and look for thefollowing entries.

2. Alter the entries as follows:
Set "network.http.pipelining" to "true"
Set "network.http.proxy.pipelining" to "true"
Set "network.http.pipelining.maxrequests " to some number like 30. This means it will make 30 requests at once. You can set this value in to any number but i guess 30 would be more than enough..

3. Lastly right-click anywhere and select New à Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on information it receives.
