Lots of duplicated code in proxy.go

[Username404-59]

The following snippet:

proxy.Config.RLock()
defer proxy.Config.RUnlock()

appears around 12 times

Edit: I put the wrong label, this is not a bug

So what do you propose?
The snippet as is can not be extracted to a function/method. This is because the defer makes the following statment execute once the function exits.

So every snippet of this:

proxy.Config.RLock()
defer proxy.Config.RUnlock()

is actually something like for example this:

proxy.Config.RLock()
// some code
if someVariable {
  proxy.Config.RUnlock()
  return
}
// some more code
proxy.Config.RUnlock()

The only way I see how this code snippet could be removed is by creating a middleware method/function similar to how the http packet operates. However, I don't think removing a snippet like this would warrant such a major refactor since it would not add much benefit. Locking and immediately deferring to unlock a ReadLock is pretty much standard procedure.

This got already addressed in the rewrite (#114). But thanks for pointing it out.
