in this case is google consider as a doorway page?

see 1's url

this is original url

http://www.josh18.com/showstory.php?id=282801

now i add some text here add after the url

http://www.josh18.com/showstory.php?id=282801&pagesomtexy

now if google Cached(index) both page so is it spam or doorway page?

note: please open both url and chek both url diff. i add end of the url &pagesomtexy extra

 

This won't be doorway page; however you gonna have duplicate content issue since two urls having same content.

 

is it going to duplicate content?

so how can i solve this type of problem?

 

waiting for proper answer.
