(HTML) Functions of the http-equiv meta-attribute

HTML Has an attribute called HTTP equiv which has 2 functions against versions 4 and 5. The placement of the HTTP equiv is always in the head tags of the website, as these attributes are part of the Meta tags.
2 functions that are in this attribute are refresh and encoding (on the right on the character set used).
If you’ve ever seen a website that has a page refresh menu or in Indonesian, it’s an update. Many of them use this HTTP equivalent meta. For example, as with ebuddy, the settings display the menu.
Note the code below!
Meta HTTP equiv. Update
It is clear the components used are Update, and on the number 60 is a countdown of seconds, so 60 seconds is 1 minute and you can edit it however you want.
The http-equiv attribute provides information (HTTP headers) or component body values. Can be used to simulate the response from (HTTP Header) well. Application examples in HTML versions 4 and 5 can be found below!
HTML 4.xx
HTML5:
The difference from here is the content coding used, which HTML4 must use Meta HTTP Equip Content Type enter directly in HTML5 Meta charger without having to select the coding type.
The bottom line is that HTML5 is better than HTML4, but because of this advantage, many websites don’t use HTML5 as not all browsers can read HTML5 content except Firefox and the like.
Quite complicated and easy to understand HTTP equiv. And if you have any questions about the above please comment
Hopefully useful and good luck
