Today i typed my website url in the browser like i am giving example http://www.listing.com/ourcompany.aspx/images/ourcompany.aspx and it gives no error and return ourcompnay.aspx page in my browser i was very shocked i thought it should give me a 404 error that page not found........th en i open some other websites and try their url's to be double for example http://www.sikkerhet.c om/ourcompany.aspx/test/ourcompany.aspx and http://www.sikkerhet.c om/ourcompany.aspx/images/ourcompany.aspx and http://www.sikkerhet.c om/ourcompany.aspx/product.aspx and these gives error 404 that page not found.......i thought there might be a filtering in iis7 which i don't know but i should have that in my website........ ...if anybody knows about it kindly help and discuss this matter in detail here whether i am wrong or not.
