仅针对浏览器的 DLL 注入

Question

I want to be able to type www.mydomain.com into my web browser but have the actual traffic go to something.mydomain.com. I thought to, maybe inject a dll into the process browser(firefox.exe). I tried to use some methods like hooking, dll injection using create remote thread etc. But, since I'm a newbie, especially when it comes to C++ or Assembly level languages, I coudn't understand much about it. The one's I could understand are no longer compatible with Win 7 or higherCould someone help me by directing me in the right path. All I want is know how to intercept/manipulate an outgoing URL request from the browser. I found that TCP/IP first creates some socket using socket() function and then connect() function. I sthere a way to intercept that? I want this to be easy, simple and compatible with windows XP to 10. If it's not easy I'm okay with building different codes for different versions. If the script is cross platform, it would be even more awesome.

I don't think what you want to do (or more precisely the way you want to do it) is possible without being the owner of the domain and setting a HTTP redirect on the server.

Modifying the hosts file or setting up your own DNS server and having the machine or its router use that to resolve DNS queries is really the only way but...

Dependant on the browser this may not be possible. Current versions of firefox and chrome implement dns prefetching which essentially means that they come preloaded with a bunch of popular dns entries for faster page loading times.
