In 2004 I wrote an article on devpapers.com about installing ColdFusion Express on Linux. I made a point of providing links to where Linux and Windows versions of ColdFusion Express could still be downloaded from the allaire.com domain. They worked all the while after Macromedia bought Allaire, but now that Adobe has bought Macromedia, those links no longer work.
Alas I don't have a Linux copy, but from my ColdFusion Express book I have the Windows version from the CD rom. And now I will provide this from my site as long as I don' t hear from any lawyers as to why I can't redistribute free software ;)
