Looking for an Apache server to take a URL request - Pass to a PHP page (mod_rewrite) for parsing. The pieces of the query string that are parsed need inserted into a MySQL database. The original request is reverse proxied to another domain with the same parameters. The response from the other domain is parsed and inserted into the database and then returned to the requestor. The objective is to be a broker for a transaction that is processed by another domain and record the data flow. This is just a very small proof of concept
Open to NGINX as well.
