title: iOS uiwebview goBack history control
body: <p>I am loading a "webpage1" on an uiwebview and saving its first request on an instance variable "webviewHistory". Then, I must reuse that webview to load another page, "webpage2" (saved its first request to "webviewHistory" too), and history should start now from this request. Problem is if I execute goBack (button IBAction) from "webpage2", I can keep going back to "webpage1" history and following. 
  If I check request and compare with initial saved, works! but not with redirections, for example, if I trigger request to www.youtube.com, request is redirectioned to m.youtube.com and first one is not saved as navigation history! how to solve it?  </p>
  
  <pre><code>if (![webViewSocial.request.URL.absoluteString isEqualToString:self.webviewHistory]){
      [webViewSocial goBack];
      }
  </code></pre>
