[web-devel] Re: wai-fastcgi

[Michael Snoyman]

Of course, there's always the easy way: spawn-fcgi[1]. I just stumbled upon
it, this seems like the "right way."

Using this, I think I'll try to add a nginx section to the deploying
page[2], and maybe even get some benchmarks between lighttpd and nginx.
Seems like Cherokee could also fit the bill here.
