Hi I am wondering about including external files in a php page.
I know how to include the file, My question is more about overheads doing that would potentially cause. Would that in effect double my bandwidth usage fro instance, by including a page from another server? eg. would i then be getting data uploaded to my server(from the include) and also data downloaded (by the user). or does the data gathered by the include go directly to the user?
I know on a small scale it probably isnt a factor but on a busy site, would this be an issue?
