well, ok, I run a web-server mostly running Apache.

apart from MediaWiki, most of the content thus far is static pages and files.

so, not really some huge/complicated web-app thing, nor does it interact with any other servers (it contents are pretty much all self-contained, ...).

I had generally imagined web-servers mostly like they were file-servers, but with the plus-side of having a defined browser-level interface, and the ability to use scripts or binaries to generate contents.

for a client-side app (probably a traditional desktop-style application), it would use an HTTP server mostly like a file-server for retrieving updated resources and similar. a CGI script could mostly exist to provide a manifest and so the client app can know if/what files to download.

dunno about an app working in a browser, I haven't personally really looked much into this. the one thing I had noted which I felt might make this worthwhile was "Google Native Client", but given it is Chrome-only at this point, this is a drawback (better if Firefox supported it, but the FF people apparently oppose it).

Adobe Flash sometimes seemed like a possible option, but isn't particularly compelling, and the development environment apparently costs money.

but, generally, I more prefer the desktop application experience... Received on Sat Jan 26 2013 - 20:22:11 CET
