Well, I started using Apache and I 've already understood how it works, and it's very simple to use (or it's just me that easily learns anything about computers), but I think that a the next version of HFS should have support for PHP because HFS is a program that is quickly configured by it's GUI and with it anyone can quickly share files through HTTP protocol, and if I need to go somewhere and have to share a file into the internet, it's a program like HFS that I'd use because simply by drag-dropping files to the shared file list the files are automatically shared, so it's quicker that setting an Apache server from nothing. Also, Apache needs registry changes and runs as a windows service so, for permanent use it's more usefull as is uses less memory and CPU usage than HFS (because of the HFS's GUI), but on public computers, most times it's not possible to make any change in windows registry (not even dreaming on setting a windows service, though it's also about the registry), and so only with HFS it would be possible to share files because (if wanted) it doesn't use windows registry.
I just wanted to make clear that, though I'm now using Apache (as I said above), HFS is a very good program, and I changed to Apache because HFS doesn't support PHP (yet), so you'd maybe hurry the PHP/ASP support for HFS and make it a even better program.
