title: Why 127.0.0.1:8080/wp jump into 127.0.0.1/wp automatically?
body: <p>My wordpress was built on 80 port of apache2.<br>
  Now i change apache2 configuration file,to make port 80 into 8080,
  everytime i input <code>127.0.0.1:8080/wp</code>  in the firefox  ,it jump into 127.0.0.1/wp automatically, in order to visit my post,i have to input 
  url in the  form of <code>http://127.0.0.1:8080/wp/?p=1938</code> ,it will not jump into <code>http://127.0.0.1/wp/?p=1938</code>,i wander what result in the jump from <code>127.0.0.1:8080/wp</code> into <code>127.0.0.1/wp</code> .<br>
