What server-side web language/framework do you recommend for use on an embedded device? The device is similar to a linksys wireless router. Ideally I am looking for a framework that is fast, efficient, and will run well on a device with limited resources (CPU, Memory, etc).
Some initial considerations are PHP, Django, or even mod_perl.
Justin, It sounds like your platform has relatively a lot of horsepower. For this reason, I'd say go with the framework you're most comfortable with. PHP and mod_perl are plenty fast and efficient. It really depends on what modules are available for the http server that you're running.
Your question led me to take a peek at the framework that tomato firmware uses for their web interface. Their server is micro_httpd/mini_httpd with cgi extensions, and the pages are asp. There is also some javascript thrown in. Here's a link to tomato firmware where you can download the source and have a look for yourself. If your device is similar to a wireless router, you should check out other router firmware projects, such as dd-wrt, openWRT, and sveasoft.

I would suggest LUA (http://www.lua.org). Barracuda (http://barracudaserver.com) has a webserver with LUA support, but it's not free.
