I need to disallow some URLs on my site but I am not sure how to do that. I have a site that has products and reviews.  When someone makes a review, the site generates a URL automatically like this:

mysite.com/addreview_1.htm
mysite.com/addreview_2.htm
....
mysite.com/addreview_9999.htm


I need some way to disallow all the URLs which will appear in the future.


Question: Possessive-S/apostrophe in a list, including the first and second person
Answer: It should be "Mary's and your house"  (note the change of order for the owners). http://www.grammarbook.com/punctuation/apostro.asp .

I think it should be "John's, Mary's and my house"  or "John and Mary's and my house" but the later implies that John and Mary are connected in some way in addition to the joint house ownership.

However, if possible I would reword the sentence so that "your house" or "our house"  sufficed.
