I'm pretty sure that gzip compression is already natively and transparently
supported in AOLserver as long as you build and include the ns_zlib module.
You shouldn't ever have to bother with encoding or calling a special
function; rather, you just need to enable it in the config file: "ns_param
gzip on" in the ns/server/${server} section of your config file (there's
also a gzipmin param to set the minimum size required in bytes to trigger
compression).One problem is that AOLserver doesn't gzip content when ns_return is called; it works for pretty much every scenario except that one. I don't know why this is the case; we just hacked this by recompiling nsd to always gzip regardless of the config file, as long as the client supports it (line 161 of connio.c). It would be nice if this worked correctly by default (or if we figured out the proper way to enable its use in ns_return).
