I want to modify the header of all HTTP requests going through a proxy to inject some attributes into the header. I'm not planing any virus/hack/fishing, I need to test a software who has to receive some user data (id, access control params) for each http request. I cannot log in to the system since the authentication/authorization mechanism cannot be used for test purposes.
So for any http request I want to intercept it at the proxy and add attributes to the header which will help me simulate a logged user with specific credentials.
Do I need to program a servlet myselft or does any one knows of something (like HAProxy, but for windows).
thank you
