PHP poser, can this be done?

Happen to be experimenting which has a search powerplant which fits my purpose well and will allow me to put a research box on any other site in the event that it’s for the same host or definitely not.When somebody makes a search they tend to be taken towards the search outcomes page on the webpage where the actual script is installed, but i used to be wondering if you find a way the fact that search site could have a connection which will take the person back into the site they first completed the seek out on

Use session or piece of food to remember the connect to the earliest site.
