Are there any URL shorteners or redirectors whose target links can be changed by its creator after it was made?
I'm asking because in some cases, I might want to change the target link of a shortened URL to a newer one (or if the old one went dead). It might be hard to edit where the links were posted. e.g. links in readme.txt files or manuals included with files available for download, or if one has posted the link in many different forums or message boards. It would be easier to just edit the target link.
I've tried many of the popular URL shorteners: bit.ly, goo.gl, is.gd, j.mp, tinyurl.com - among others, but they don't seem to be able to do this.
