need help with irule for magento shopping cart

I'm not familiar with this product, but I suspect that Chris is on to something here. Without seeing some of the specifics of this application (HTTP headers, for example) it's a little hard to say for sure though.

 

 

It's common for app servers to dynamically build redirects based on the request port numbers. Since BigIP translates this when terminating SSL, the app server can sometimes make poor assumptions about where it's supposed to send users. The good news is that most of them give you some provision to tell the app server that it's behind a proxy device, which will usually help matters.
