META-tags offer more possibilites than promoting your site to search engines. You can also identify yourself as the author of the document:
<META NAME=”author” CONTENT=”Nora Tol”>
As well as claim the copyright of it:
<META name=”copyright” content=”Nora Tol Virtual Publishing”>
But there’s more. For instance you can effect the caching of the browser. The caching function within a browser should help increasing the speed of surfing the Net. All the files needed to make up your website are downloaded to a persons’ computer and stored in the caching of the browser. When the visitor returns their second visit should be quicker. Some files are not downloaded from the server anymore, but are used from the cache function. It could cause for people not being able to see the newest version of the site. If you update your website more than once a day, you would want to disable this. META tags allow you to set an expiration date for your website:
<META HTTP-EQUIV=”expires” CONTENT=”Mon, 12 Feb 2001 08 :21 :57 GMT”>
When the expiration date is reached, the browser will look for the latest version.
You could also completely disable caching:
<META HTTP-EQUIV=”pragma” CONTENT=”no-cache”>
When using frames you could allow pages to jump out of frames automatically by using a window-target:
<META HTTP-EQUIV=”window-target” CONTENT=”_parent”>
You could also use other values with the CONTENT attribute like _top, _ self or a frame name.
To refer one page to another, you can use the following:
<META HTTP-EQUIV=”refresh” CONTENT=”3;URL=http://www.noratol.nl”>
The three after CONTENT are seconds. After 3 seconds you’ll get redirected to the URL, in this case http://www.noratol.nl is.
