if url not exists then redirect to another url

[vitamint]

Hi,

i need a help to redirect my website.

i have hosted my site in 2 servers. form first server i just redirect the site to second server using php header code i.e.:

header("Location: http://www.mydomain.com/secondserver/index.php");

now sometimes my second server goes down. For this time period i want to locate the site to first server.

In my word i can say this way:

Task to do from first server
1. check if second server running or not. if running then redirect the page to second server.
2. if second server not running then locate the url to first server

please help!

thanks in advance

Try using [man]fsockopen/man to open a connection to a remote server on port 80. If the connection fails, the server doesn't seem to be online or is not responding.

You can use an if() statement to check if the socket connected. If it did, disconnect the socket (since you don't need to send anything) and redirect the user to that server. If not, redirect them to a different server.
