Good but require golden function Rated 4 out of 5 stars
Good software but require some feature
2. Should be able to show real address e.g. www.abc.com/download/236 redirect to server3.abc.com/xcfdfds32dfs/filename.zip
It should able to show the latter too (Now cant).
3. Should really be able to manage server
3.1 Add more depth: now it cant set server3.abc.com (it'll be abc.com instead) why not? Just let it - and I suggest you choose regular expression instead of wildcard pattern.
3.2 MUST compare with real address 
- which makes us can manage 1 connection per server in same domain. No need to so smart that guess server3.abc.com is abc.com so cut it as abc.com while abc.co.xx is abc.co.xx. Just receive user input. We know what we did.
I regist account just to review your plugin :) Good job
