Dynamic meta tag depending on URL?

[arunrajiah]

Is it possible to have dynamic meta tag depending on URL?

Ex:

If i have www.example.com

<meta name="example" content="example">.

If it is home.example.com

<meta name="example" content="home example">

both URL redirects to same html page.

Please help

Perfectly possible. On a small site store the data in an array. On a big site use a database.

However, I have to ask 'where does redirecting come into things?' You're either serving a page or sending a redirect.

I suspect he either means a rewrite or solves to the same page.

As g1smd says it is possibly, but will require some sort of server side scripting language. What scripting language is available on the web server.

Ouch. If you're rewriting more than one URL to show the same content, you've got bigger problems than how to word the <meta> tag.

But yes, I think it can be done in about four lines of javascript, since that's where we are.

[arunrajiah]

I have done using the below javascript

window.getSelection ? yourTag.name= ‘tagname' : yourTag.Name= ‘tagname '
yourTag.content='example.com';
document.getElementsByTagName('head')[0].appendChild(yourTag);

[g1smd]

That sounds like a very bad idea.

Do you mean the javascript itself or the rewrite?

[Fotiman]

JavaScript is not the place to be doing this. What's the point of rewriting meta data about the document after you've already started serving the document? For one thing, those without JavaScript will end up getting different meta data (think about search engines). But even more importantly, if you've got home.example.com serving the same content (or nearly the same, if you take meta data into account), as example.com, then (as lucy24 pointed out) you're going to dilute the value of your content in the eyes of search engines.

Which is why my original question to him was "What scripting language is available on the web server."
Client site scripting is not a good solution as Fotiman's pointing out.
