I have a website application where the users will perform tasks that will send request to other servers.
I wish those request to be performed through the users own IP and am therefore looking for a way to solve this issue, eg make sure that it is not my servers ip that are visible to the other servers.
One way of solving this would be that the user installed a browser plugin that serves as a proxy server, as the middle hand between the applications request and the other server.
Is this possible to do or will I stumble into hidden security blocks? Where would I begin to check for solutions?
