how to cache resources in html


HTML cache application is a useful property, that makes web resources accessible if you are offline. Also, this property makes apps load faster, because cashed resources usually load faster. Besides, the browser will only get changed data from the server. Amazing!

Try it Yourself (preview):
Click Here

Download full project here:
Click Here

How to cache web applications?
To cache resources, you need to include a manifest file with an html tag in your html file.
Example:
<!DOCTYPE HTML>
<html manifest="manifest.appcache">
...
</html>

Manifest has many extensions, but the recommended one is .appcache

How to create this manifest file?
The manifest file is a simple text which is composed from 3 sections:
-The first section is NETWORK : this is specified for including files that mustn't be cached, like login files and sign-up files, that contains database passwords...
Example:
NETWORK:
login.php

-The second section is Cache Manifest: this is specified for tagging files that will be cached, such as javascript resources and images...
Note: Cache Manifest first line is required
Example:
CACHE MANIFEST
/style-sheet.css
/animated-picture.gif
/jQuery.js

-The third section is FALLBACK : this is for specifying fallback pages if you are offline.
Example: in the manifest code below, cache.html will be served to replace all files in the /admin/ directory.
FALLBACK:
/admin/ /cache.html

Hope that helps, enjoy

Hello and welcome back in our blog.
By curiosity, today's post will be about the longest email address in the world.
The image shown below contains the Longest Email Address.

longest email in the world

This Email Address contains more than 345 letters, with a long domain name and username.
So this is what is like:

contact-admin-hello-webmaster-info-services-peter-crazy-but-oh-so-ubber-cool-english-alphabet-loverer-abcdefghijklmnopqrstuvwxyz@please-try-to.send-me-an-email-if-you-can-possibly-begin-to-remember-this-coz.this-is-the-longest-email-address-known-to-man-but-to-be-honest.this-is-such-a-stupidly-long-sub-domain-it-could-go-on-forever.pacraig.com

due to, the length of this email address, it seems that it's impossible to memorize it, also this email is very useful because you can get rid of spam messages.

See you in next post.
