PEAR is a framework and distribution system for reusable PHP components.


D:\xampp\php\PEAR\Net\Curl.php

Net_Curl([URL], $_SERVER['HTTP_USER_AGENT']);

Speed up your web pages with YSlow

sandeepverma — Sat, 15 Nov 2008 17:55:14 +0000

First download/install firefox add-ons Firebug and YSlow

1. Make Fewer HTTP Requests

Combined files are a way to reduce the number of HTTP requests.
CSS Sprites are the preferred method for reducing the number of image requests.
Image map combine multiple images into a single image.

2. Use a Content Delivery Network

Intermediary caching is cache between the browser and the server, so use CDN like facebook
fbcdn.com.

3. Add an Expires Header

For static components: implement “Never expire” policy by setting far future Expires header.
For dynamic components: use an appropriate Cache-Control header to help the browser with conditional.

Expires: how long the web content cacheable.
max-age: the browser will request the new content after the age limit.

Header add “Expires” “Mon, 15 Nov 2020 00:00:00 GMT”
Header add “Cache-Control” “max-age=31536000″

4. Gzip Components

mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*

5. Put CSS at the Top

6. Move Scripts to the Bottom

7. Avoid CSS Expressions

background-color: expression( (new Date()).getHours()%2 ? “#B8D4FF” : “#F08A00″ );

8. Make JavaScript and CSS External

9. Reduce DNS Lookups

10. Minify JavaScript

RewriteRule ^css/(.*\.css) combine.php?type=css&files=$1
RewriteRule ^js/(.*\.js) combine.php?type=js&files=$1

11. Avoid Redirects

12. Remove Duplicate Scripts

13. Configure ETags

This is the unique identifier for comparing cached files.

FileETag none

More page optimization techniques are here below:

http://developer.yahoo.com/performance/rules.html

Make Ajax Cacheable
Flush the Buffer Early
Use GET for AJAX Requests
Reduce the Number of DOM Elements
Split Components Across Domains
Minimize the Number of iframes
No 404s
Reduce Cookie Size
Use Cookie-free Domains for Components
Choose over @import
Optimize Images
Don’t Scale Images in HTML
Make favicon.ico Small and Cacheable
Keep Components under 25K
