Permalink
A permalink (portmanteau of permanent link) is a URL that points to a specific web page, often a blog or forum entry which has passed from the front page to the archives, or the result of a search in a database. Because a permalink remains unchanged indefinitely, it is less susceptible to link rot. Most modern weblogging and content-syndication software systems support such links. Other types of websites use the term permanent links, but the term permalink is most common within the blogosphere. Permalinks are often rendered simply, so as to be human-readable.
History
Originally, all hyperlinks were permalinks, as content was static. However, when many web pages became dynamic, this was often no longer the case.
One cited early use of the term permalink in its current sense was by Jason Kottke on March 5, 2000, in a post titled: "Finally. Did you notice the".Matt Haughey had discussed a permalink style feature with Blogger co-founders Evan Williams and Paul Bausch the previous weekend, and Bausch had pointed out that it was technically feasible to produce permanent links in Blogger, using a feature (written by him) that allowed the ID of a post to be placed in a Blogger template. In response to Kottke's blog, on March 6, 2000, Matt Haughey posted the technical details on his own weblog, which helped open the way to widespread adoption.
