This page describes two initiatives, which purposes are to make it easier for users to install a program, when browsing the web.
A good explanation is available in the package description :
Package providing apt:// Protocol
aptlinex : This addon allows installing Debian packages from iceweasel, firefox, galeon or konqueror just clicking on a web link. ?BR ?BR For this to work, links need to have an url beginning with apt:// This package does not install the packages or download them from the web sites, it just launches apt, passing the package name to install as a parameter to apt.
aptlinex is packaged in Debian Lenny, but it won't be installed by default.
http://gambas.gnulinex.org/linexapt/ aptlinex (linexapt)'s Homepage.
The URL looks like this : apt://linexapt. It isn't possible to install multiple package at once.
It's inclusion in Debian was discussed in [http://lists.debian.org/debian-devel/2008/03/msg00330.html debian-devel] mailing list.
apturl : Has a similar purpose, but isn't included in Debian.
The URL looks like this : apt://,apturl,aptlinex. It is possible to install multiple package at once.

- Some people consider that those product make it too easy to install a package (and therefore they have security concerns).
Most publication system (wiki, forums, etc...) don't allow arbitrary URLs, So they have to be configured to allow apt:// URLs.
