The site I am developing loades the search results of several other search engine (specifically travel engines) I post all results using IFRAMES embedded in DIVs. That means I load all results at one and a menu allows the user to select the layer (with particular vendor's results) he wants to see. If someone has a slower connection, the request sometimes times out on the vendor's site and the user would have to reload the frame in order to get the results. What I am thinking is that maybe if I preload all search results serversided, maybe I could then somehow pass the results on to the user, once they finish downloading on the server side. The user would only be waiting for my server to show the results and not for the vendor's server.
Take a look, www.travelgrove.com just use the air search, it's not completely done but mostly works.
Thanks for all your support, if you can point me into the right direction that would be great.
