问一个问题 不知道是不是问题 ,就是CSDN forumID=c5eca554-e88a-47bd-873d-58c8014f2f91 后面这一串字符,有什么用

我有这样的问题 是因为看到有这几个网站他们都把标题根到 url连接后面

http://www.lightinthebox.com/sequined-bateau-neck-sweep-brush-train-evening-dress-inspired-by-evan-rachel-wood-at-the-emmys_p283066.html

文章有这样的标题 :Sequined Bateau Neck Sweep/Brush Train Evening Dress Inspired By Evan Rachel Wood At The Emmys

http://www.lightinthebox.com/A-line-One-Shoulder-Short--Mini-Chiffon-Cocktail-Dress_p169421.html
文章有这样的标题:A-line One Shoulder Knee-length Chiffon Cocktail Dress

http://stackoverflow.com/questions/11060192/command-to-call-method-from-viewmodel
文章的标题为:Command to call method from viewmodel

根着后面是为做什么才根到后面哟??
