I have done or was part of some mobile projects that are uploaded in their respective markets and currently live, and I am already mentioning status as LIVE for respective projects.One of my friend -who is actually a web developer- has recently suggested me to put the urls of the application if the project is live. And I am taking this suggestion seriously. But i have found that some urls are really long and they desperately need to be shortened. So my question is : Is it fair to shorten all the urls of the live application? Or just shorten those which are so long.In case I shorten all the urls, can any employer take this point negatively? Thanks EDIT : After reading your response I think I need to clarify one thing.... The applications I have developed are mobile applications and they are uploaded in their respective markets, like Blackberry App store and android markets. It means a lot for an application accepted to be sold in market. And I want to put the url of these market sites. The links are there for a long time, so there is no threat that the link goes offline in a year or two..... 
Is it fair to use shortened url to mention and give links of live projects in my resume?

How many of these sites do you have? I can guarantee that a prospective employer is not going to click on more than 2 or 3.Rather than listing them all on your CV, I would set up a portfolio website, where you can list all of your projects. Include a screenshot, a description of the project, your role, a link, etc etc.Then put a link to that in your CV. That way, you can have a fairly short portfolio URL (just yourname.com or something) and it doesn't matter how long the links to the other sites are.
