Hi Paul
Thanks for the quick reply.
I am using php / MySQL which does work fine, and I appreciate your comments about security - we don't actually store any personal information on users but it is still an important issue to bear in mind.
My biggest concern is over performance. At the moment the data is flowing as such:
Request for facebook page (? -> US)
Request from facebook page to app (US -> UK)
App makes FQL (proprietry facebook SQL) calls (UK -> US)
App makes SQL calls (UK -> UK)
App returns rendered HTML (UK -> US)
Page returned to user (US -> ?)
Are the secured servers that you mention dedicated? Cost is also a factor and a
dedicated server would be quite expensive at this time. Given the viral growth of facebook apps this could be an option further down the line but at present the load is not great, which is why I mentioned other hosts as perhaps someone has experience of hosting facebook apps in the US with more success, or has used webhostinguk and experienced no problems?
Regards
