We need to redirect certain visitors to our website based on their IP address(es). Here's the catch:
Most of our website is a Yahoo store, which offers very limited functionality regarding server side includes, etc. In fact I don't think any standard SSI calls such as <!--#echo var="REMOTE_ADDR" --> are supported. It doesn't appear to parse PHP code either.
How can I redirect these users away from our pages to another site based on their IP address? Can I embed an iframe or something similar on my pages that will load my redirect code from another server? If so, how can I take over the main browser window and move it to another IP address or site?
