I have a very simple server running WAMP on a Windows machine, with PHP code which is a simple API for my clients that returns XML. The things is that the hardware is very modest, and if a user calls the link to the API and hits F5 many times (calls the link repeatedly) the server performance goes down a little (response time goes up). Is there a way to limit the queries to port 80?
I know how to limit this in the the PHP code, but I think is not a good practice because even if I limit the queries on the PHP code the query is already made, and I'm consuming resources checking with PHP.
