How to redirect user based on domain requested?

Anon

Hello,

I have been trying to work out how to redirect a site visitor based on the domain name included in the document they request.

i.e. if the user requests

http://abc.com.au/

I can push them to

http://myserver.com.au/abc/

If anyone knows how to do this, please let me know (please cc by e-mail if possible).

Many thanks,

Jessica

Sounds like your trying to write a re-direct for a virtual server. Most virtual server setups can be done at the HTTPD level (configuration in APACHE).

If you want to do this yourself, you have to look at an environment variable sent by HTTP/1.1 compliant browsers called HTTP_HOST. This variable will contain the domain name of the request. You can use this in code to send a header() redirect to the subdirectory or even specific page that you want.

Hope this helps.

Hi Rich,

Yes, that's exactly what I want to do. I'm trying to be cheap and avoid the costs associated with name virtual host setups from my ISP. :-)

If you want to do this yourself, you have
to look at an environment variable sent by
HTTP/1.1 compliant browsers called
HTTP_HOST. This variable will contain the

the subdirectory or even specific page that
you want.

That's great - I don't suppose you'd be able to give me an example of the code I might use?

Basically, at this stage I only want a single index.php page on the site (doc root) which will handle the redirections. I'd rather not have to go through the learning curve (or trial and error) to figure this out.

Sorry if that sounds lazy... :-)

Thanks for your help so far,

Jess

example:

<?PHP

switch ($HTTP_HOST) {

case "www.firstdomain.com":
header("Location: /firstdirectory/index.php");
break;

case "www.seconddomain.com":
header("Location: /seconddirectory/index.php");
break;

case "www.thirddomain.com":
header("Location: /thirddirectory/index.php");
break;

default:
header("Location: site_index_page.html");

)

Note the default page at the end. You should have a page like this in the root directory that has links to the individual site directory/pages. This is because old browsers that are not HTTP/1.1 compliant do not set the HTTP_HOST environment variable. I have also seen some crappy proxies convert directly to the IP, so this helps with that problem as well.

Hope this helps,

Hi Rich,

Thanks for that, you're a gem!

I changed Location: to specify a URL rather than a directory - this has the added advantage of the new domain dislaying in the address bar, which is more like name virtual hosting.

Thanks for taking the time to help me out on this - I know there are others looking for this too!

Hi Jessica,
I hope you can help me
I am trying to count how many times a user click on a link. Do you know how can I increment a counter each time the user click on the link, and then redirect him to the link?
Any idea is very welcome. Thanks

Sorry, I can't help you with that. The PHP example I quoted was sent to me by someone else.

Thanks. I'm using your code. I noticed the the final ")". i thought it was a typo but i tried it both ways and php doesn't seem to care if it's a ")" or a "}"

thanks again
