We'd like to enable this functionality so that we can prevent IP leak of our IPs when users force our server to make requests such as with a file upload. We're using cloudflare on the frontend but want to prevent our server from exposing our incoming IP when making outgoing connections. We're looking to accomplish this with ip routing:

The site to be tested for the major desktop/mobile and browser combinations 2. The fix for those mobile/desktop combinations 3. There is a birth day dropdown that doesn't look good on mobile devices and I need that to be fixed. These are the major issues I am having and I need those to be fixed as soon as possible. The ideal candidate would be the one who has extensive experience with Responsive design and knows how to fix browser issues without breaking the existing and working ones I need a person who has good communication skill and would detail his methodology as well.

We run our web application on a Linux platform with Apache2 web server and a Java-based application server named 'Coldfusion'. They are communicating via mod_proxy. Sometimes, apparently with no reason, Apache stops forwarding requests to Coldfusion. Actually, it doesn't crash, it simply stops working, while its processes are still up. We can't manage to find the root cause of the problem, but some apache error logs grabbed our attention. The goal of this job is to fully understand this issue and fix it permanently.
